[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The ADAMS-based spring operating mechanism fault analysis method provided in the embodiment of the present invention utilizes the Automatic Dynamic Analysis of Mechanical Systems (ADAMS) virtual prototype technology to perform three-dimensional modeling and dynamic simulation on the CT26 spring operating mechanism, and analyzes the influence of the mechanism fault on the pneumatic parameters, and obtains the dynamic parameter changes of the operating mechanism under typical fault conditions, which provides a theoretical basis and technical support for the design optimization and fault prevention of the spring operating mechanism.

[0037] The spring operating mechanism fault analysis method based on ADAMS can be applied in Figure 1 In an application environment, the client communicates with the server through a network. Exemplarily, taking the medical health scenario as an example, the target user (manager or R&D personnel) can upload the basic structural data of the spring operating mechanism through the client. Accordingly, the server can obtain the basic structural data of the spring operating mechanism through the client, and can establish a three-dimensional simulation model of the spring operating mechanism based on the basic structural data based on the automatic dynamics analysis of the mechanical system ADAMS, obtain the three-dimensional simulation model of the spring operating mechanism, and perform dynamic simulation on the three-dimensional simulation model of the spring operating mechanism based on ADAMS to obtain the connecting rod stroke and speed curve, thereby performing dynamic characteristic analysis on the spring operating mechanism based on the connecting rod stroke and speed curve to obtain dynamic parameters and characteristic analysis results, and then performing fault factor analysis on the spring operating mechanism based on the dynamic parameters and characteristic analysis results to obtain fault factor analysis results, and the fault factor analysis results are fed back to the client. Accordingly, the client can receive the fault factor analysis results from the server, and can display the fault factor analysis results on the client for the target user to query or browse. By adopting the ADAMS-based spring operating mechanism fault analysis method provided in the present application, the accuracy of the fault factor analysis results for the spring operating mechanism can be effectively improved.

[0038] The client may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, and portable wearable devices. The server may be implemented by an independent server or a server cluster consisting of multiple servers. The present invention is described in detail below through specific embodiments.

[0039] See also Figure 2 As shown, Figure 2 A schematic flow chart of a spring operating mechanism fault analysis method based on ADAMS provided in an embodiment of the present invention comprises the following steps:

[0040] S10: Acquire basic structural data of the spring operating mechanism.

[0041] Among them, the basic structure data may include but is not limited to component geometry data, such as the number of spring coils, wire diameter, free length, cam size and profile parameters, ratchet teeth number and diameter, energy storage shaft, output crank arm and other components of the size and shape information; material property data, such as each component material density, elastic modulus, Poisson's ratio, yield strength, hardness and other parameters; connection and assembly data, such as the connection method between components (such as key connection, pin connection, welding, etc.), assembly sequence, assembly clearance or interference and other data, this application does not impose any restrictions on this.

[0042] It should be noted that the spring operating mechanism can use the spring as the power source, and the energy storage unit is driven by a motor to stretch the spring to store energy. When the opening and closing command is received, the electromagnet is actuated to open the trip latch, the energy holding latch is released, the energy of the opening and closing spring is released, and the transmission part is pushed to complete the opening and closing operation.

[0043] This application is explained by taking the CT26 spring operating mechanism as an example, which does not constitute a limitation on this application. The CT26 spring operating mechanism has the characteristics of small size, compact structure, stable closing power, high reliability, and long mechanical life. The CT26 spring operating mechanism adopts an integral cast aluminum alloy frame, which is light in weight and has good rigidity; the overall design structure is simple, the integration is high, the number of parts is small, and the transmission efficiency is high; the parts are processed with high precision, and the overall quality is stable and reliable.

[0044] S20: Based on the automatic dynamics analysis of mechanical systems ADAMS, a three-dimensional simulation model of the spring operating mechanism is established according to the basic structure data to obtain a three-dimensional simulation model of the spring operating mechanism.

[0045] To establish a three-dimensional simulation model of the CT26 spring operating mechanism, we can simplify the mechanism, extract key components to build the model, combine it with actual product mapping and drawing construction, delete the parts that do not participate in mechanical movement, and use the software pre-processing function to realize its function.

[0046] Specifically, we can use ADAMS virtual prototype technology to build a simulation model for the key components of the CT26 spring operating mechanism to study the stress conditions during the closing process. Simplify the model, highlight the key structural mechanical characteristics, and extract key components to build a three-dimensional model. For example, Figure 3 As shown, this application surveys the shape and size of the parts of the CT26 spring operating mechanism of Shandong Taikai High Voltage Switch Co., Ltd., combines the manufacturer's drawings, and uses ADAMS to build a model. Due to the large number of parts and complex coordination, this application deletes the energy storage motor, opening and closing coils and other parts that do not participate in mechanical movement, and uses the ADAMS software pre-processing function to realize its functions.

[0047] Optionally, the geometric model of each component, such as ratchet, pawl, cam, roller, spring, etc., can be established in ADAMS software according to the actual size and structure of the CT26 spring operating mechanism. In the modeling process, the accuracy and completeness of the geometric model must be ensured for subsequent dynamic simulation analysis.

[0048] It should be understood that, based on the automatic dynamics analysis of mechanical systems ADAMS, the three-dimensional simulation model of the spring operating mechanism is established according to the basic structure data to obtain the three-dimensional simulation model of the spring operating mechanism, which refers to the process of how to establish the three-dimensional simulation model of the spring operating mechanism. Among them, in step S20, that is, based on the automatic dynamics analysis of mechanical systems ADAMS, the three-dimensional simulation model of the spring operating mechanism is established according to the basic structure data to obtain the three-dimensional simulation model of the spring operating mechanism, including the following steps:

[0049] S21: Determine the stiffness coefficient of the spring operating mechanism according to the basic structure data;

[0050] S22: Based on Hooke's law and the stiffness coefficient, determining force-related data and energy-related data of the spring operating mechanism;

[0051] S23: Determine boundary condition data and constraint pair data of the spring operating mechanism according to the force-related data and the energy-related data;

[0052] S24: Determine a three-dimensional simulation model of a spring operating mechanism according to the stiffness coefficient, the boundary condition data and the constraint pair data.

[0053] When using ADAMS to set parameters for the 3D simulation model of the spring actuator, the spring stiffness coefficient is a key parameter. The spring stiffness coefficient determines the deformation characteristics of the spring when it is subjected to force and reflects the ability of the spring to resist deformation. Accurately setting the spring stiffness coefficient in the model is crucial to realistically simulate the behavior of the spring during the operation of the actuator.

[0054] Optionally, the stiffness coefficient can be determined based on the physical properties of the spring such as the material and geometric dimensions (such as the shear modulus of the material, the diameter of the spring wire, the major diameter of the spring, the number of effective coils of the spring), so as to be accurately set based on the parameters of the actual spring rather than arbitrarily estimated, thereby improving the accuracy of the model.

[0055] Optionally, the process of determining the stiffness coefficient of the spring operating mechanism according to the basic structure data may refer to the following formula:

[0056]

[0057] Among them, K represents the stiffness coefficient of the spring operating mechanism; G represents the shear modulus of the material; d represents the diameter of the spring wire; d2 represents the major diameter of the spring; and n represents the number of effective turns of the spring.

[0058] Optionally, the shear modulus of the 40Cr material is 8.3846e10Pa. Combined with the closing and closing spring parameters of the CT26-110kV spring operating mechanism, the stiffness coefficient and preload parameters are calculated as shown in Table 1. The parameters in the table are added to the simulation model to complete the construction of the dynamic simulation model.

[0061] Hooke's law can be used to establish a quantitative relationship between the external force on a spring and the spring deformation. In the dynamic simulation of a spring operating mechanism, Hooke's law can be used to calculate the force generated by the spring based on the spring stiffness coefficient and the known deformation, or to calculate the spring deformation based on the force. Optionally, the formula for Hooke's law can be as follows:

[0062] F=KΔx

[0063] Among them, F represents the spring force; K represents the stiffness coefficient of the spring operating mechanism; Δx represents the spring compression.

[0064] It is understandable that, after the stiffness coefficient of the spring operating mechanism is known, the force generated by the spring can be calculated according to the deformation of the spring in combination with Hooke's law. For example, during the energy storage process of the spring operating mechanism, as the spring is compressed, by measuring or setting the compression amount, the force corresponding to the elastic potential energy stored in the spring at this time can be calculated. This force will act on other components in the mechanism, thereby affecting the dynamic process of the mechanism.

[0065] In dynamic simulation, Hooke's law can be used to analyze the relationship between spring deformation and mechanism motion. For example, during the closing or opening action of the mechanism, the deformation of the spring will cause a change in force, thereby pushing the moving parts of the mechanism. Hooke's law can be used to link the spring deformation with the kinematic parameters of the mechanism's connecting parts, such as displacement and velocity. Assuming that the spring stiffness coefficient and the external force acting on the mechanism are known, the spring deformation can be calculated based on Hooke's law, and then how this deformation affects the motion of the connecting parts can be analyzed, such as calculating the stroke of the connecting rod.

[0066] Furthermore, the elastic potential energy of the spring can be calculated in combination with Hooke's law to understand the energy conversion process of the spring operating mechanism. In the energy storage stage, the energy stored in the spring can be calculated; in the energy release stage, by comparing the change in elastic potential energy with the increase in the kinetic energy of the mechanism, the energy conversion efficiency between the spring and other parts of the mechanism can be analyzed, thereby evaluating the performance of the mechanism.

[0067] That is to say, Hooke's law plays a key role in the energy storage and release process of the spring operating mechanism. For example, in the energy storage stage, when the spring is compressed or stretched, the elastic potential energy stored in the spring can be calculated according to Hooke's law; in the energy release stage, such as the closing or opening process, Hooke's law can be used to analyze how the energy released by the spring is converted into the kinetic energy of the mechanism, thereby driving the movement of the mechanism.

[0068] During the working process of the spring operating mechanism, the relationship between the force and deformation of the spring is an important factor affecting the dynamic characteristics of the mechanism. Using Hooke's law, the force exerted by the spring on other parts of the mechanism under different working conditions (such as different degrees of compression or stretching) can be accurately simulated in the model, thereby more realistically reflecting the actual working process of the mechanism, such as the closing speed, opening speed, and the interaction force between the various components.

[0069] Optionally, Hooke's law can assist in setting the boundary conditions and constraints of the model. When considering the contact and interaction between the spring and other components, the magnitude and direction of the spring force (determined by Hooke's law) can be used as boundary conditions to define the contact force between the components. For example, when setting the contact constraint between the cam and the roller, if the spring force acts on the cam through the transmission component, the spring force calculated according to Hooke's law can be used as the initial force when the cam contacts the roller, thereby more realistically simulating the force conditions and motion state of the mechanism in actual work, and this application does not impose any restrictions on this.

[0070] The force applied to the spring will affect the motion boundary conditions of the entire operating mechanism. For example, the magnitude and direction of the spring's elastic force may determine the start and end positions of certain components, the boundaries of the motion speed change, etc., which can be used as boundary condition data. At the same time, based on the actual motion relationship and force transmission path between the various components of the mechanism, combined with the mechanical properties of the spring, the constraint pair data can be determined. For example, if the spring's elastic force causes a component to rotate around a certain axis, it can be determined that a revolute pair needs to be set here; if the component is made to move in a straight line, a translation pair may need to be set, etc.

[0071] It should be understood that determining the boundary condition data and constraint sub-data of the spring operating mechanism according to the force-related data and the energy-related data refers to the process of how to determine the boundary condition data and constraint sub-data of the spring operating mechanism. Wherein, step S23, that is, determining the boundary condition data and constraint sub-data of the spring operating mechanism according to the force-related data and the energy-related data, includes the following steps:

[0072] S231: Determine the ratchet rotation angle data, the first rotation pair between the ratchet and the first support shaft, and the gear pair in the energy storage stage according to the force-related data and the energy-related data;

[0073] S232: Determine the closing spring compression data and the moving pair in the energy storage stage according to the force-related data and the energy-related data;

[0074] S233: Determine the rotation-related data of the closing pawl in the closing stage and the second rotation pair between the closing pawl and the second support shaft according to the force-related data and the energy-related data;

[0075] S234: Determine, according to the force-related data and the energy-related data, the opening latch rotation-related data in the opening stage, and the third rotation pair between the opening latch and the third support shaft;

[0076] S235: Determine the boundary condition data and constraint pair data of the spring operating mechanism based on the ratchet rotation angle data, the first rotating pair, the gear pair, the closing spring compression data, the moving pair, the closing latch rotation related data, the second rotating pair, the opening latch rotation related data and the third rotating pair.

[0077] In the process of setting the boundary conditions of the three-dimensional simulation model of the CT26 spring operating mechanism, the action process of the CT26 spring operating mechanism can be analyzed. Among them, the action process of the CT26 spring operating mechanism is divided into the following three stages: energy storage stage, closing stage and opening stage. In order to realize the above movement process, an ideal constraint pair can be added to the simulation model. Optionally, the ideal constraint is usually a constraint pair with physical meaning, such as a revolute joint, a translational joint, a gear joint, etc. Exemplarily, the main constraint pairs added to the simulation model mentioned in the present application can be shown in Table 2 below:

[0078] Table 2

[0079]

[0080] Optional, energy storage stage: With the help of energy storage motor or manual energy storage, the ratchet is driven to rotate and the closing spring is compressed at the same time until the roller on the ratchet is buckled on the arc surface of the energy storage retaining latch. To avoid the dead point of the circle, it should be rotated 185°.

[0081] It is understandable that the rotation angle of the ratchet during the energy storage phase can be regarded as a boundary condition. If the ratchet is required to rotate 185°, the boundary of the ratchet's range of motion during the energy storage process is clarified. This angle limits the end position of the energy storage phase, and also ensures that the mechanism can avoid the dead point of the circle to ensure that subsequent actions can proceed smoothly. In the simulation model, this boundary condition can be achieved by setting the ratchet's revolute pair to limit its rotation within a specific angle range.

[0082] The compression process of the closing spring also implies boundary conditions. From the initial state to the state where the roller is buckled on the arc surface of the energy storage retaining latch, this process defines the range of spring deformation, which can be used to determine the boundary range involved in the subsequent calculation of the spring force (according to Hooke's law) and the elastic potential energy stored in the spring.

[0083] Optionally, during the process of the energy storage motor or manual energy storage driving the ratchet to rotate, a rotating pair, i.e., the above-mentioned first rotating pair, can be provided between the ratchet and the shaft supporting it (such as the first supporting shaft). For the process of compressing the closing spring, if there is a component that causes the closing spring to produce axial compression, a moving pair can exist between the component and the spring. If gear transmission is involved in the energy storage stage to achieve energy transfer or speed regulation, for example, the output shaft of the energy storage motor drives the ratchet to rotate through a set of gear transmissions, a gear pair can be provided between the mutually meshing gears.

[0084] Optionally, during the closing phase: when a closing command is received, the closing electromagnet pushes the closing latch to rotate counterclockwise to allow the energy storage holding latch to make way for the ratchet. The energy storage holding latch is pushed away by the roller on the ratchet to disengage the ratchet, thereby releasing the energy of the closing spring to close the circuit.

[0085] The direction of rotation of the closing latch (counterclockwise) and the purpose of rotation (to clear the position of the energy storage latch) can constitute boundary conditions. The direction and purpose of the above action restrict the movement mode and sequence of related components during the closing process. In the model, boundary conditions can be reflected by setting constraint pairs between the closing latch and other components and defining trigger conditions (receiving the closing command), that is, only when these conditions are met can the closing action be carried out in the prescribed manner.

[0086] The energy storage keeps the latch pushed open and the ratchet released, and this action process also has boundary conditions. This action process stipulates the order of power transmission and component movement within the mechanism during the closing stage, that is, when the closing electromagnet is activated, the subsequent components must move in this order to release the energy of the closing spring, so as to accurately simulate the dynamic characteristics of the closing process.

[0087] Optionally, the closing electromagnet pushes the closing latch to rotate counterclockwise, and a rotation pair should be set between the closing latch and the shaft supporting it (such as the second support drawer), that is, the above-mentioned second rotation pair. During the process of releasing energy from the closing spring, if there is relative linear motion between components, for example, some connecting rods produce linear motion under the action of spring force, a moving pair can be set between the connecting rods or between the connecting rods and other components to simulate the linear motion.

[0088] Optional, opening stage: after closing, the buckle pin on the large crank arm buckles onto the closing latch, and makes the closing latch rotate counterclockwise, so that the roller on the closing latch buckles onto the opening latch. When receiving the opening command, the opening electromagnet pushes the opening latch to rotate counterclockwise to make way for the closing latch, and the closing latch is pushed away by the roller on the large crank arm and released, and the opening spring releases energy to open the circuit.

[0089] The action of buckling the connecting pin on the large crank arm may cause the closing holding latch to rotate counterclockwise, and the process of the roller buckling on the opening latch can be regarded as the starting boundary condition of the opening stage. The sequence and method of the above actions determine the state and relationship of each component at the beginning of the opening action.

[0090] The process in which the opening electromagnet pushes the opening latch to rotate counterclockwise, so that the closing holding latch is pushed away and released by the large crank arm roller can be regarded as the key action boundary of the opening stage. This process clarifies the movement direction, power transmission path and action sequence of each component in the opening process, thereby determining the boundary conditions of the opening action in the simulation model, such as the starting conditions for the opening spring to release energy.

[0091] Optionally, the opening electromagnet pushes the opening latch to rotate counterclockwise, and a rotation pair, i.e., the third rotation pair, is provided between the opening latch and the support shaft (such as the third support shaft) to simulate its rotational motion. When the opening spring releases energy, if linear motion between components is involved, such as the linear motion of certain transmission rods during the opening process, a moving pair can be provided between the transmission rods or between the transmission rods and other components to accurately simulate the linear motion.

[0092] With the stiffness coefficient to describe the physical properties of the spring, the boundary condition data to specify the range and limit of the mechanism, and the constraint data to determine the connection and movement between the components, a complete 3D simulation model of the spring operating mechanism that can truly reflect the physical properties and movement behavior of the spring operating mechanism can be constructed in the ADAMS software. In this 3D simulation model of the spring operating mechanism, the movement, force and energy changes of each component can be accurately simulated and analyzed through the previously determined data.

[0093] S30: Performing dynamic simulation on the three-dimensional simulation model of the spring operating mechanism based on ADAMS to obtain the connecting rod stroke and speed curve.

[0094] Based on ADAMS virtual prototype technology, the simulation model is dynamically simulated, and a point is selected on the connecting rod as the mark point. The opening and closing springs provide energy to enable the mechanism to operate. During the simulation, the opening and closing spring parameters are adjusted without applying external loads, so that the connecting rod stroke and speed curve can be obtained.

[0095] Optionally, a dynamic simulation analysis is performed based on the above simulation model. The CT26 spring operating mechanism is powered by the opening and closing springs, so during the simulation process, only the opening and closing spring parameters need to be adjusted without applying external loads. Figure 4 As shown in the figure, when simulating the closing process of the spring operating mechanism, a Mark point should be selected on the operating mechanism to reflect its kinematic characteristics.

[0096] like Figure 5 As shown, the simulation analysis obtains the connecting rod stroke and speed curve, among which the over-stroke displacement of the connecting rod is 0.43cm, the maximum displacement of the connecting rod is 7.88cm, and the closing time meets the mechanism action standard.

[0097] S40: Based on the connecting rod stroke and the speed curve, a dynamic characteristic analysis is performed on the spring operating mechanism to obtain dynamic parameters and characteristic analysis results.

[0098] After obtaining the connecting rod stroke and the speed curve, the dynamic characteristics of the key components of the spring operating mechanism can be further analyzed, such as the contact force characteristics of the cam and the roller, the mechanical characteristics of the energy storage shaft and the force characteristics of the output crank arm, so as to conduct a comprehensive characteristic evaluation, such as the smoothness of the mechanism movement and the energy transfer efficiency, etc. This is beneficial for the subsequent steps to diagnose and predict the faults of the spring operating mechanism based on the above-mentioned dynamic parameters and characteristic analysis results.

[0099] Optionally, the embodiments of the present application are illustrated by further analyzing the contact force characteristics of the cam and roller, the mechanical characteristics of the energy storage shaft, and the force characteristics of the output crank arm of the spring operating mechanism, which does not constitute a limitation to the present application.

[0100] It should be understood that, based on the connecting rod stroke and the speed curve, the dynamic characteristic analysis of the spring operating mechanism is performed to obtain the dynamic parameters and the characteristic analysis results, which refers to the process of how to obtain the dynamic parameters and the characteristic analysis results. Among them, in step S40, that is, based on the connecting rod stroke and the speed curve, the dynamic characteristic analysis of the spring operating mechanism is performed to obtain the dynamic parameters and the characteristic analysis results, including the following steps:

[0101] S41: Based on the connecting rod stroke and the speed curve, a dynamic characteristic analysis is performed on the spring operating mechanism to obtain dynamic parameters and characteristic analysis results, including:

[0102] S42: Based on the connecting rod stroke and the speed curve, the contact force between the cam and the roller of the spring operating mechanism is analyzed to obtain the contact force related dynamic parameters and motion stability analysis results;

[0103] S43: Based on the connecting rod stroke and the speed curve, the mechanical distribution characteristics of the energy storage axis of the spring operating mechanism are analyzed to obtain torque-related dynamic parameters, stress-related dynamic parameters and energy transfer stability analysis results;

[0104] S44: Based on the connecting rod stroke and the speed curve, performing a force analysis on the output crank arm of the spring operating mechanism to obtain force-related dynamic parameters and force change rate analysis results;

[0105] S45: Determine the dynamic parameters and characteristic analysis results based on the contact force-related dynamic parameters, the motion smoothness analysis results, the torque-related dynamic parameters, the stress-related dynamic parameters, the energy transfer stability analysis results, the force-related dynamic parameters and the force change rate analysis results.

[0106] The dynamic characteristics analysis of different components of the operating mechanism is performed separately, such as the so-called first round of dynamic characteristics analysis, which may include but is not limited to the contact force analysis of the cam and roller, the mechanical distribution characteristics of the mechanism energy storage shaft and the force analysis of the output crank arm.

[0107] Among them, the contact force analysis of the cam and the roller: during the closing process, the energy storage spring releases energy, the ratchet drives the cam and the roller to collide violently, and drives the middle crank arm to rotate to complete the closing. The cam and the roller collide with severe force. Analysis of the mechanical distribution characteristics of the energy storage shaft of the mechanism: The energy storage shaft is a key component that connects the cam, ratchet, overrunning clutch and other parts. When closing, it rotates rapidly in the overrunning clutch to provide energy. Force analysis of the output crank arm: The output crank arm connects the output joint, output shaft and piston rod, and is the most complex part in the mechanism action.

[0108] Since the spring operating mechanism is an interrelated whole system, the movement of the connecting rod can be a comprehensive reflection of the movement and force transmission of the various components inside the mechanism. The contact force between the cam and the roller is one of the key factors that can affect the movement of the mechanism, and its effect can be transmitted to the connecting rod through the mechanical transmission link.

[0109] The resultant force on the entire mechanism can be inferred from the acceleration of the connecting rod. Further, through the kinematic and dynamic models of the mechanism, combined with parameters such as the mechanical transmission ratio, the source of the force can be gradually traced, such as the size of the contact force between the cam and the roller. For example, if it is known that the acceleration of the connecting rod at a certain moment is large, and it is determined through analysis that the acceleration of the mechanism movement is caused by the energy transfer after the cam and the roller come into contact, then it can be inferred that the contact force between the cam and the roller is also large at this time based on the transmission relationship and the mass of the moving parts.

[0110] Observe the mutation point and change slope of the connecting rod speed curve. When the cam contacts the roller, it will cause a sudden change in the internal force of the mechanism, which will be reflected in the connecting rod speed curve. The time period from the stable state to the mutation of the speed curve can be roughly inferred as the contact time between the cam and the roller. For example, if the speed curve rises or falls sharply in a short period of time, this time period may correspond to the contact process between the cam and the roller, so that the action time of the contact force can be preliminarily estimated.

[0111] By analyzing the change cycle of the speed curve of the connecting rod during multiple closing or opening operations, the frequency of the mechanism movement can be determined. Since the contact between the cam and the roller is periodic and related to the overall movement frequency of the mechanism, the frequency of the contact force between the cam and the roller can be analyzed based on the periodic change of the speed curve of the connecting rod. For example, if the speed curve of the connecting rod shows a change pattern of one cycle per T seconds, when it is determined that the mechanism movement is closely related to the cam-roller contact, it can be inferred that the frequency of the contact force between the cam and the roller is 1 / T, and this application does not limit this.

[0112] According to the contact force and contact time between the cam and the roller, the energy transfer during the collision between the cam and the roller can be analyzed. When the contact force is large and the contact time is appropriate, the energy transfer efficiency may be high. Combined with the speed change of the connecting rod, the energy efficiency of the energy storage mechanism transferred to the transmission mechanism through the cam and the roller under different contact force conditions can be evaluated. For example, if the speed of the connecting rod can quickly rise to a large value after the cam and the roller contact, and remain stable, it means that the energy transfer efficiency is high; on the contrary, if the speed rises slowly or fluctuates, it may mean that energy is lost during the contact process and the transfer efficiency is low.

[0113] Analyzing the smoothness of the connecting rod speed curve can reflect the smoothness of the mechanism's movement. The size and change pattern of the contact force between the cam and the roller will affect the smoothness of the mechanism's movement. If the contact force fluctuates greatly, it will appear as frequent jitters or sudden changes in speed on the connecting rod speed curve. By analyzing the speed curve, the impact of the cam-roller contact force on the overall smoothness of the mechanism's movement can be evaluated. For example, when the contact force between the cam and the roller is uneven, it may cause sawtooth fluctuations in the connecting rod speed curve, which indicates that the mechanism's movement is not smooth, and further analysis of factors such as the contact state and wear of the cam and the roller is required.

[0114] Optionally, the torque of the energy storage shaft can be estimated based on the kinematic parameters (speed and acceleration) of the connecting rod and the transmission ratio of the mechanism. During the mechanism action, such as the closing or opening stage, the dynamic change of the energy storage shaft torque can be inferred by analyzing the changing slope of the connecting rod speed curve. By observing the periodic fluctuations or irregular jitters of the connecting rod speed curve, the fluctuation characteristics of the energy storage shaft torque can be analyzed. The fluctuation characteristics of the torque can reflect the smoothness of the mechanism movement and the stability of energy transfer, which is not limited in this application.

[0115] According to the connecting rod stroke and speed curve, combined with the geometric structure of the mechanism and the principle of material mechanics, the stress distribution of the energy storage shaft can be predicted. The prediction of stress distribution can help determine the weak links of the energy storage shaft during operation. Using the dynamic parameters of the connecting rod, the stress magnitude of the energy storage shaft can be estimated. By comparing the estimated stress magnitude with the allowable stress of the energy storage shaft material, a safety assessment can be performed, and this application does not impose any restrictions on this.

[0116] The energy transfer efficiency of the energy storage shaft can be analyzed through the speed curve of the connecting rod. For example, when the energy storage shaft provides power to move the connecting rod, if the connecting rod can quickly reach a higher speed and remain stable, it can be shown that the energy transfer efficiency of the energy storage shaft is high; on the contrary, if the speed of the connecting rod increases slowly or there is obvious energy loss during the movement (such as the speed gradually decreases), it means that there is loss in the energy transfer process, which can indicate that the energy transfer efficiency is low.

[0117] By observing the stability of the connecting rod speed curve, the stability of the energy storage shaft during energy transfer can be evaluated. If the speed curve is stable without obvious fluctuations or mutations, it means that the energy storage shaft is relatively stable during energy transfer and can provide continuous and stable energy support for the mechanism; on the contrary, if the speed curve fluctuates greatly, it may mean that there are unstable factors in the energy storage shaft during energy transfer, such as torque fluctuations, loose connections between components, etc., which require further analysis and resolution.

[0118] Optionally, the force on the output crank arm can be estimated based on the movement of the connecting rod (stroke and speed curve) and the relationship between the kinematics and dynamics of the mechanism. When the speed curve of the connecting rod changes, such as a sudden change in speed or a change in acceleration, the change in the magnitude of the force on the output crank arm can be inferred. By analyzing the changes in the speed curve of the connecting rod throughout the movement cycle, the peak and mean values ​​of the force on the output crank arm can be determined. At the same time, by calculating the average value of the force during the entire movement cycle, the average load of the output crank arm under normal working conditions can be understood, which helps to analyze its fatigue life and working reliability.

[0119] According to the stroke and speed curve of the connecting rod, combined with the geometric structure and motion relationship of the mechanism, the direction of the force on the output crank arm can be inferred. In different action stages of the mechanism, such as closing and opening, the force direction of the output crank arm may change, which helps to evaluate the stability and reliability of the output crank arm in complex motion processes, and reasonably design its structural shape to adapt to forces in different directions.

[0120] By observing the periodic changes in the speed curve of the connecting rod, the frequency of force changes on the output crank arm can be analyzed. By analyzing the relationship between the frequency of force changes on the output crank arm and the operating frequency of the mechanism (such as the operating frequency of closing and opening), the dynamic load characteristics of the output crank arm during long-term operation can be understood. If the frequencies of the two are close or equal, the output crank arm may work at a resonant frequency, increasing the risk of fatigue damage.

[0121] Optionally, the dynamic characteristics analysis can be performed separately on different components of the operating mechanism, such as the so-called second round of dynamic characteristics analysis, which may include but is not limited to the influence of closing spring stress relaxation failure on closing speed, the influence of cam wear on part load peak, and the influence of mechanism jamming on dynamic parameters.

[0122] Among them, the influence of closing spring stress relaxation failure on closing speed: spring stress relaxation reduces the preload, resulting in a decrease in the initial acceleration of the mechanism parts, prolonging the closing time and affecting the operation of the circuit breaker. The influence of cam wear on the peak load of parts: the cam and the roller collide violently during closing, and the cam wear will make the stress condition more severe, affecting the performance of the operating mechanism. The influence of mechanism jamming on dynamic parameters: the intermediate arm roller is prone to jamming. By adjusting the friction coefficient between the roller and the roller shaft (0.05-0.15) to simulate the jamming fault, the closing process is simulated and analyzed.

[0123] Results related to the effect of closing spring stress relaxation failure on closing speed: Through analysis, the specific change value of closing speed before and after closing spring stress relaxation can be obtained; by plotting the closing speed change curve over time, the difference between the curves under normal and stress relaxation states can be compared; combined with the spring elastic potential energy formula, the effect of the change in spring stiffness coefficient caused by stress relaxation on energy release can be analyzed.

[0124] Results related to the impact of cam wear on peak load of parts: By determining the changes in the peak load of parts that interact with the cam (such as rollers, crank arms, etc.) before and after the cam wear, it is helpful to evaluate the impact of cam wear on the load-bearing capacity of parts; through dynamic analysis, the changes in the time and position of the peak load of parts during the movement cycle of the mechanism are obtained; after the cam wears, the contact force distribution between it and other parts is analyzed.

[0125] Relevant results of the study on the influence of mechanism jamming on dynamic parameters: Study the rate of change of dynamic parameters such as speed, acceleration, and force when the mechanism jams; Analyze the increase in energy loss caused by mechanism jamming, and evaluate the influence of this energy loss on the overall performance of the mechanism by calculating the difference in energy loss before and after the jamming; Observe the influence of mechanism jamming on the motion cycle and the motion phase of each component, and by recording and analyzing these changes, evaluate the degree of damage to the overall coordination and working reliability of the mechanism by the jamming, which is not restricted in this application.

[0126] Optionally, the key mechanical and load distribution characteristics of different components can be obtained by studying the dynamic characteristics of different components of the operating mechanism, that is, the contact force analysis of the cam and roller, the mechanical distribution characteristics of the mechanism energy storage shaft, and the force analysis of the output crank arm are respectively conducted on the operating mechanism. During the closing process of the operating mechanism, the energy storage spring releases energy, and the ratchet drives the cam to rotate and violently collide with the roller to drive the intermediate crank arm to rotate and complete the closing action. The spring operating mechanism transmits the energy in the energy storage mechanism to the transmission mechanism through the collision between the cam and the roller. As a key component connecting the two major systems, the collision force between the cam and the roller is relatively severe.

[0127] For example, the contact force load spectrum of the cam and roller collision is as follows: Figure 6 In the energy storage system of the spring operating mechanism, the energy storage shaft is a key component connecting the cam, ratchet, overrunning clutch and other parts. During the closing process of the mechanism, the energy storage shaft rotates rapidly in the overrunning clutch to provide energy for the operating mechanism. Figure 7 The load spectrum of the energy storage shaft and the overrunning clutch connection position. In the spring operating mechanism, the output crank is connected to the output joint, output shaft and piston rod, which are the parts with the most complex forces during the mechanism operation. Figure 8 This is the force load spectrum of the hole on the crank arm during the closing process of the spring operating mechanism.

[0128] S50: performing a fault factor analysis on the spring operating mechanism according to the dynamic parameters and the characteristic analysis result to obtain a fault factor analysis result.

[0129] It is understandable that the present application can perform fault factor analysis based on kinematic anomalies (such as abnormal stroke or speed, etc.), or based on dynamic anomalies (such as abnormal force or energy, etc.), or based on abnormal characteristics of key components (such as cams and rollers, energy storage shafts or output crank arms, etc.), and the present application does not impose any restrictions on this.

[0130] It should be understood that, performing fault factor analysis on the spring operating mechanism according to the dynamic parameters and the characteristic analysis results to obtain the fault factor analysis results refers to the process of how to obtain the fault factor analysis results. Among them, step S50, that is, performing fault factor analysis on the spring operating mechanism according to the dynamic parameters and the characteristic analysis results to obtain the fault factor analysis results, includes the following steps:

[0131] S51: performing fault factor analysis on the cam and the roller according to the dynamic parameters and the characteristic analysis results, and obtaining wear fault data, fatigue crack fault data and poor contact fault data;

[0132] S52: performing a fault factor analysis on the mechanism energy storage shaft according to the dynamic parameters and the characteristic analysis results to obtain fatigue fracture fault data, deformation fault data and loosening fault data;

[0133] S53: performing a fault factor analysis on the output crank arm according to the dynamic parameters and the characteristic analysis result, and obtaining overload damage fault data, fatigue failure fault data and loose connection fault data;

[0134] S54: performing a fault factor analysis on the closing spring according to the dynamic parameters and the characteristic analysis result to obtain spring fault data;

[0135] S55: Determine the fault factor analysis result based on the wear fault data, the fatigue crack fault data, the poor contact fault data, the fatigue fracture fault data, the deformation fault data, the loose fault data, the overload damage fault data, the fatigue failure fault data, the loose connection fault data and the spring fault data.

[0136] Among them, the high contact force generated by the violent collision between the cam and the roller is an important factor causing wear. If the contact force is too large and exceeds the wear resistance limit of the material, the contact surface of the cam and the roller may gradually wear out. Wear will change the geometry of the cam and the roller, affecting the contact state and force transmission between them. For example, the worn cam profile may cause uneven force on the roller, which in turn affects the energy transmission efficiency and may even cause jamming.

[0137] Frequent impact forces will cause fatigue in the materials of the cam and roller. Under the repeated action of contact force, the microstructure inside the material will gradually be damaged, forming fatigue cracks. The fatigue cracks will expand with the increase in the number of working times. When the cracks expand to a certain extent, they may cause sudden breakage of the components and cause failure of the operating mechanism.

[0138] If the cam and roller have dimensional accuracy problems or improper installation during the manufacturing process, coupled with the impact force, poor contact between them may occur. Poor contact will cause fluctuations in the energy transfer process and cause instability in the mechanism movement. For example, partial contact may cause excessive local stress, accelerate wear and fatigue processes, and also affect the rotation stability of the intermediate arm, thereby affecting the normal closing action.

[0139] During the closing process of the mechanism, the energy storage shaft rotates rapidly in the overrunning clutch, and the complex stress distribution inside it may lead to fatigue fracture. If there are defects in the design or manufacturing process of the energy storage shaft, such as stress concentration points (such as the shoulder, near the keyway, etc.), fatigue cracks are likely to occur in this part when it is subjected to alternating stress for a long time (the magnitude and direction of stress constantly change during rotation), which may eventually lead to the fracture of the shaft and make the operating mechanism unable to work normally.

[0140] The energy storage shaft is subjected to various forces and may bend and deform. If the bending deformation exceeds the allowable range, it will affect the matching accuracy of the energy storage shaft and other parts (such as cams, ratchets, etc.), resulting in additional losses and vibrations during energy transfer. For example, the deformed energy storage shaft may cause the rotation angle of the cam to deviate, thereby affecting the accurate transmission of energy during the closing process and the normal operation of the mechanism.

[0141] Since the energy storage shaft transmits torque during operation, if the fastening force of the connecting parts (such as keys, couplings, etc.) is insufficient, they may become loose under the action of torque. Loosening will cause abnormal relative movement between the energy storage shaft and the connected parts, affecting energy transmission and the stability of the mechanism, and may even cause damage to other parts.

[0142] The output crank arm is the part that is subjected to the most complex forces during the mechanism operation. When the combined force exceeds its designed load-bearing capacity, overload damage will occur. For example, during the closing or opening process, if there is an abnormal impact force or a sudden change in load, the output crank arm may deform, break, or suffer other faults, which will directly affect the normal operation of the mechanism.

[0143] The force on the output crank arm changes dynamically, and this repeatedly changing force will cause fatigue in the output crank arm. After multiple operations, fatigue accumulation may cause material performance degradation, cracks to appear and gradually expand. Especially in areas where force is concentrated (such as the root of the crank arm, near the connection hole, etc.), the risk of fatigue failure is higher. Once fatigue failure occurs, the output crank arm will not be able to transmit force normally, resulting in mechanism failure.

[0144] Since the output crank arm connects multiple parts, the connection parts (such as bolts, pins, etc.) may become loose during long-term force application. Loose connections will reduce the matching accuracy between parts, generate gaps, and cause deviations in force transmission, which will affect the movement accuracy and stability of the mechanism. For example, looseness between the output joint and the output crank arm may cause changes in the direction and magnitude of the output force, affecting the movement of the piston rod and the performance of the entire mechanism.

[0145] During the long-term working process of the closing spring, due to repeated compression and stretching, the microstructure inside the material changes, resulting in a decrease in elastic properties and stress relaxation. The aging and degradation of the material is an inevitable natural process, but if it exceeds the normal aging rate, it may be related to the quality of the material itself or the use environment. Harsh environmental conditions such as high temperature and high humidity will accelerate the aging of the closing spring material. For example, in a high temperature environment, the atomic diffusion rate of the spring material is accelerated, and the lattice structure is more likely to change, resulting in a decrease in the elastic modulus and an increase in stress relaxation, which affects the closing speed.

[0146] If the initial design parameters of the closing spring (such as spring stiffness, effective number of turns, wire diameter, etc.) do not meet the actual working requirements, it may cause stress relaxation to occur more easily during use. For example, if the spring stiffness is designed to be too large, the internal stress will be too high under long-term stress, which will accelerate stress relaxation. Process defects in the spring manufacturing process, such as uneven quality of spring steel wire and improper heat treatment process, will affect the mechanical properties of the spring. For example, improper heat treatment may cause residual stress inside the spring steel wire. During use, these residual stresses are superimposed on the working stress, accelerating stress relaxation, and thus affecting the closing speed.

[0147] Friction between the cam and other components is one of the main causes of wear. If the lubrication conditions are not good, the friction coefficient increases, and the cam surface will gradually wear during the relative motion with the roller and other components. This wear will change the profile of the cam and change the peak load of the parts. Poor lubrication may be caused by a failure in the lubrication system, improper grease selection, or contamination of the lubricating grease by impurities such as dust in the working environment. During the long-term periodic force process of the cam, the surface material may suffer from fatigue wear. Especially when the contact stress is large, micro cracks will be generated inside the material, which will gradually expand and cause material peeling, thereby aggravating the cam wear and affecting the load distribution of the parts.

[0148] During the operation of the mechanism, if impurities such as dust, sand, and metal chips in the surrounding environment enter the mechanism, friction and blockage will occur between the moving parts, causing jamming. When the lubricating grease is contaminated, its lubrication performance decreases, and granular impurities may be generated, aggravating the wear and jamming between the parts. Among them, contamination may come from leakage during the operation of the equipment or the intrusion of external pollutants.

[0149] Due to long-term stress, overload or temperature changes, the components in the mechanism (such as shafts, connecting rods, crank arms, etc.) may be deformed. The deformed components will change the movement trajectory and matching relationship of the mechanism, resulting in jamming between the moving parts. The wear of the moving parts will change the matching clearance between them. When the wear reaches a certain extent, the fit may be too tight or interference may occur, causing jamming.

[0150] Through comprehensive analysis of the above aspects, we can fully understand the possible failure factors of the spring operating mechanism and provide a basis for fault diagnosis, prevention and maintenance.

[0151] Optionally, the influence of mechanism failure on the mechanism dynamic parameters can be studied to obtain the changes in the dynamic parameters of the operating mechanism under different failures. The influence of the stress relaxation failure of the closing spring on the closing speed of the mechanism is studied. When the spring is subjected to constant strain for a long time, the dislocations, vacancies and other defects inside the material will gradually move and rearrange over time to reduce the total energy of the system. This process will cause the stress inside the spring to gradually decrease, that is, the stress relaxation phenomenon of the spring. The stress relaxation of the spring represents the change in its preload. The preload of the closing spring under different stress relaxation conditions is calculated based on the parameters of the opening spring, as shown in Table 3 below.

[0152] Table 3

[0153]

[0154] After the spring operating mechanism completes energy storage, the energy that drives the mechanism to complete the closing action comes from the closing spring, and the stress relaxation of the closing spring will reduce its preload, resulting in a decrease in the initial acceleration of the mechanism parts, prolonging the closing time of the operating mechanism, thereby affecting the normal operation of the circuit breaker. For example, the closing time and closing speed of the spring operating mechanism under different degrees of stress relaxation faults are simulated and analyzed. Fig. 9 shown.

[0155] The influence of cam wear on the peak load of parts is studied. During the closing action of the spring operating mechanism, the cam collides violently with the roller under the action of the closing spring. Combined with the load spectrum of the mechanism parts in the previous section, it can be seen that the various parts of the mechanism are generally subjected to an impact load at this time point, which will directly cause wear on the cam parts, and the cam wear failure will make the stress condition more serious. Such a cycle will have a greater impact on the performance of the operating mechanism. The influence of different degrees of cam wear on the peak load spectrum and impact factor is shown in the figure. Fig.10 As shown, when the cam wear degree increases from normal working conditions to 0.2mm, the peak contact force between the cam and the roller increases by 1.1kN, and the load peak changes significantly.

[0156] The effect of mechanism jamming on dynamic parameters is studied. Since the rotation of the intermediate arm roller on the roller shaft is not assisted by bearings and only lubricating oil is used to reduce friction, it is a part that is prone to jamming. Therefore, the mechanism jamming failure is simulated by adjusting the friction coefficient between the roller and the roller shaft. The roller and roller shaft of the operating mechanism are both chromium-molybdenum alloy steel, and the friction coefficient between steel and steel is 0.05-0.1 when lubricated, and 0.15 when not lubricated. Therefore, this paper simulates and analyzes the closing process of the operating mechanism when the friction coefficient is 0.05-0.15. The displacement curves and closing time of the mechanism under different friction coefficients are shown in the figure. Fig.11As shown in the figure, the increase of the friction coefficient between the roller and the roller shaft has almost no obvious change on the first half of the pull rod displacement curve during the mechanism closing process. After 35ms, the larger the friction coefficient, the smaller the pull rod speed, that is, the mechanism jamming has little effect on the acceleration stage before closing, but has a greater impact on the acceleration stage after closing.

[0157] The peak load of parts under different jamming degrees of the mechanism is as follows Fig.12 As shown, the closing process of the operating mechanism is driven by the energy storage system driving the transmission system, causing the insulating pull rod to displace to complete the closing action. However, if the friction between the roller and the roller shaft is too large, the energy storage system will use more energy to overcome the friction of the roller, and the mechanical load of the internal parts of the operating mechanism will be reduced.

[0158] This application analyzes the fault factors based on the dynamic parameters and characteristic analysis results, and can identify the cause of the fault. For example, when the closing speed of the mechanism decreases, by analyzing the closing spring stress relaxation, cam wear, mechanism jamming and other possible factors, it can be accurately determined whether it is caused by spring aging leading to stress relaxation, or cam wear changing the force transmission path, etc. This can provide a clear idea and direction for fault diagnosis, making it easier for maintenance personnel to quickly locate the fault point.

[0159] It can be seen that in the above scheme, by obtaining the basic structural data of the spring operating mechanism, based on the automatic dynamics analysis of mechanical systems ADAMS, a three-dimensional simulation model of the spring operating mechanism can be established according to the basic structural data to obtain the three-dimensional simulation model of the spring operating mechanism, and based on ADAMS, the three-dimensional simulation model of the spring operating mechanism is dynamically simulated to obtain the connecting rod stroke and speed curve, thereby performing a dynamic characteristic analysis on the spring operating mechanism based on the connecting rod stroke and speed curve to obtain dynamic parameters and characteristic analysis results, and then performing a fault factor analysis on the spring operating mechanism based on the dynamic parameters and characteristic analysis results to obtain the fault factor analysis results, which can effectively improve the accuracy of the fault factor analysis results for the spring operating mechanism.

[0160] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
