Description

Technical Field

[0001] This application relates to the field of equipment assembly technology, and more specifically, to a structural component assembly method, system, electronic device, and storage medium. Background Technology

[0002] Ship structural component assembly is the process of assembling structural components according to design technical requirements based on reference interfaces to achieve near-continuum performance, ultimately forming functional ship components. Therefore, during the assembly of ship structural components, normal stress is generated at the reference interfaces between two structural components to maintain near-continuum performance.

[0003] In related technologies, the optimal normal stress of ship structural components can be assessed based on their material properties and assembly process requirements before assembly. Then, the structural components are assembled according to the experience of the installation workers to make the normal stress at the reference interface of the structural components approach the optimal normal stress. However, in the actual implementation process, there are often certain deviations, which make the normal stress at the reference interface of the structural components too large or too small, resulting in the assembly process being difficult to meet the technical requirements.

[0004] In addition, in the complex marine swaying environment, even well-assembled structural components may experience displacement or deformation, which seriously affects the stability of the structural component assembly performance. Summary of the Invention

[0019] If abnormal values ​​occur in all candidate control positions and the sensor numbers corresponding to the abnormal values ​​are the same, it is determined that the stress sensor corresponding to the same number has failed.

[0041] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0042] It should be noted that the terms "first," "second," etc., used in this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0043] Figure 1 This is a structural schematic diagram of a structural component assembly method provided in one embodiment of this application, as shown below. Figure 1 As shown, the method includes steps 110, 120 and 130.

[0044] Step 110: Based on each candidate control position, control the drive device to drive the moving end of the fastener to move relative to the fixed end of the fastener, and obtain the normal stress measurement value between the first structural component and the second structural component under each candidate control position.

[0045] The first end of the first structural component is connected to the movable end of the fastener, and the second end is connected to the first end of the second structural component; the second end of the second structural component is connected to the fixed end of the fastener.

[0046] Specifically, the structural component assembly method provided in this application is applicable to the assembly of large structural components in mechanical equipment such as ships. These structural components are relatively large in size and need to adapt to the influence of the external environment to avoid phenomena such as displacement or deformation. Therefore, during the assembly process, a certain normal stress needs to be formed at the contact surface between two structural components to maintain near-continuum performance.

[0047] The structural component assembly method provided in this application is executed by a structural component assembly control system. This system can be implemented in software form, such as a structural component assembly control program; or in hardware form, such as a computer system that executes the structural component assembly method.

[0048] Figure 2 This is a schematic diagram of a structural component assembly provided in one embodiment of this application, as shown below. Figure 2 As shown, the first end of the first structural member 210 is connected to the movable end of the fastener, and the second end is connected to the first end of the second structural member 220; the second end of the second structural member 220 is connected to the fixed end of the fastener.

[0049] In this embodiment, taking a bolt and a nut that fits the bolt as examples, the movable end of the fastener is the bolt 231, and the fixed end is the nut 232. It can be understood that the movable end and the fixed end are opposite to each other, and the nut can also be used as the movable end and the bolt as the fixed end.

[0050] For bolt 231, it can be divided into head and screw, with the screw being a cylinder with external threads.

[0051] Both the first structural member 210 and the second structural member 220 are provided with through holes. In the first structural member 210, the through hole extends from a first end to a second end. In the second structural member 220, the through hole extends from a first end to a second end. The diameter of the through hole is greater than or equal to the diameter of the screw.

[0052] The bolt 231's threaded shaft enters from the first end of the first structural member 210 and exits from the second end of the second structural member 220, passing through the through holes of the first and second structural members in sequence. The nut 232 is threadedly connected to the portion of the bolt 231 that protrudes from the second structural member 220.

[0053] The drive device 240 is dynamically coupled to the movable end of the fastener to provide torque to the movable end of the fastener, causing the movable end of the fastener to move relative to the fixed end of the fastener. This results in a certain normal stress being generated at the contact interface between the first structural member 210 and the second structural member 220. The contact interface refers to the interface formed when the second end of the first structural member 210 is connected to the first end of the second structural member 220, and is also known as the assembly reference interface.

[0054] The drive unit 240 can have multiple candidate control positions. Each candidate control position can provide a different torque, causing the first structural member 210 and the second structural member 220 to generate normal stresses of different magnitudes at the contact interface.

[0055] A stress sensor 260 can be installed on the contact interface to measure the normal stress between the first and second structural components, obtaining the measured normal stress value. The measured normal stress value differs under different candidate control settings and varies with the candidate control setting.

[0056] The controller 250 is connected to the drive device 240 and also to the stress sensor 260 disposed on the contact surface, and is used to execute the structural component assembly method in the embodiments of this application.

[0057] The controller 250 can also be connected to the data acquisition unit 270 to acquire the normal stress measurement values ​​of the stress sensors 260. The data acquisition unit 270 can be connected to each stress sensor 260 via a signal cable or via wireless network communication to collect the electrical signals from each stress sensor 260, process them, and obtain the normal stress measurement values.

[0058] Step 120: Based on the difference between the measured normal stress value and the target normal stress value under each candidate control level, determine the target control level from each candidate control level.

[0059] Specifically, when assembling the first and second structural components, the optimal normal stress can be evaluated based on the material properties of the structural components and the assembly process requirements to obtain the target value F of the normal stress. p That is, when the normal stress between the first and second structural components reaches the target value, the structural components can achieve optimal assembly performance and are less prone to problems such as loosening and fatigue.

[0060] The measured normal stress values ​​at each candidate control setting can be compared with the target normal stress value to determine the difference between each measured normal stress value and the target normal stress value. The smaller the difference, the closer the measured normal stress value is to the target normal stress value; the larger the difference, the farther the measured normal stress value is from the target normal stress value.

[0061] The candidate control gear corresponding to the normal stress measurement value with the smallest difference can be used as the target control gear. The target control gear is the gear to be used when controlling the drive device.

[0062] Step 130 controls the drive device based on the target control gear.

[0063] Specifically, after determining the target control level, a corresponding control signal can be generated to control the drive device. At this level, the drive device drives the movable end of the fastener to move relative to the fixed end of the fastener, so that the normal stress generated at the contact interface between the first structural member and the second structural member approaches the target value of the normal stress.

[0064] During their service life, structural components are frequently affected by the environment as the operating conditions of mechanical equipment change, resulting in displacement and deformation. For example, when structural components are assembled on a ship, in the complex rolling environment of the ocean, the two structural components will shift in position, and this shift can be reflected in the changes in the normal stress between the structural components.

[0065] Therefore, the structural components can be periodically subjected to normal stress testing and assembly adjustment using the structural component assembly method provided in this application at certain time intervals, thereby ensuring the stability of the structural component assembly performance during long-term service.

[0066] Considering the material properties of structural components and the numerous influencing factors, the normal stress generated by the drive device driving the fasteners at each candidate control position can be measured during each assembly adjustment, thereby obtaining accurate normal stress measurement values ​​and improving the accuracy of structural component assembly.

[0067] The structural component assembly method provided in this application embodiment controls the driving device to move the movable end of the fastener relative to the fixed end of the fastener according to each candidate control position, and obtains the normal stress measurement value between the first structural component and the second structural component under each candidate control position; determines the target control position from each candidate control position based on the difference between the normal stress measurement value under each candidate control position and the normal stress target value; and controls the driving device according to the target control position. Since the normal stress generated between the first structural component and the second structural component by the driving device under each candidate control position is measured, the candidate control position closest to the normal stress target value is determined, thereby improving the accuracy of structural component assembly and improving the stability of structural component assembly performance during long-term service.

[0068] It should be noted that each implementation method of this application can be freely combined, rearranged, or executed individually, and does not need to rely on or depend on a fixed execution order.

[0069] In some embodiments, step 120 includes:

[0070] Based on multiple stress sensors installed on the first and second structural components, multiple normal stress measurement values ​​are obtained for each candidate control position.

[0071] Based on multiple normal stress measurements at each candidate control level and the target normal stress value, the standard deviation of normal stress corresponding to each candidate control level is determined.

[0072] The candidate control level corresponding to the minimum normal stress standard deviation is determined as the target control level.

[0073] Specifically, due to the large size of the structural components, the normal stress generated at different points on the contact interface between the first and second structural components may differ. Therefore, multiple stress sensors can be installed on the contact interface between the first and second structural components to collect the normal stress between them at each candidate control position, thereby obtaining multiple normal stress measurements corresponding to each candidate control position.

[0074] For each candidate control setting, the standard deviation of the normal stress corresponding to that setting can be determined based on multiple measured values ​​of normal stress at that setting and the target value of normal stress. This can be expressed by the formula:

[0075]

[0076] Where S is the standard deviation of the normal stress at the candidate control position; m is the number of normal stress measurements at the candidate control position, with each normal stress measurement corresponding to a stress sensor; i is the sequence number of the normal stress measurement, which can also be understood as the stress sensor number; F i For the i-th normal stress measurement, which can also be understood as the measurement value of the i-th stress sensor, F p This represents the target value for normal stress.

[0077] From all candidate control levels, the one corresponding to the minimum standard deviation of normal stress is selected and designated as the target control level. Under this candidate control level, the normal stress between the first and second structural components is closest to the target value.

[0078] The structural component assembly method provided in this application adopts the standard deviation method to determine the target control position from each candidate control position. It comprehensively considers the influence of multiple normal stress measurement values ​​under each candidate control position on the position selection, thereby improving the accuracy of structural component assembly and improving the stability of structural component assembly performance during long-term service.

[0079] In some embodiments, a plurality of stress sensors are uniformly disposed on the contact interface between the first structural member and the second structural member.

[0080] Specifically, in order to accurately measure the normal stress between the first structural member and the second structural member, it can be uniformly distributed on the contact interface between the first structural member and the second structural member.

[0081] For example, if the contact interface is circular, multiple stress sensors can be evenly arranged along the circumference. As another example, if the contact interface is rectangular, multiple stress sensors can be arranged along the four corner points and the midpoints of the four sides of the rectangle. As yet another example, if the contact interface is polygonal, multiple stress sensors can be positioned along the midpoints of each side.

[0082] A corresponding groove can be provided on the second end of the first structural component or the first end of the second structural component, according to the size of the stress sensor, for mounting the stress sensor.

[0083] The structural component assembly method provided in this application provides that multiple stress sensors are uniformly arranged on the contact interface between the first structural component and the second structural component, which can accurately measure the normal stress between the first structural component and the second structural component, thereby improving the accuracy of structural component assembly and the stability of structural component assembly performance during long-term service.

[0084] In some embodiments, the method further includes:

[0085] Obtain multiple normal stress measurements under the current candidate control gear;

[0086] If the difference between any normal stress measurement value and the average of multiple normal stress measurement values ​​is greater than a preset difference, the normal stress measurement value is determined as an abnormal value under the current candidate control level, and the sensor number corresponding to the abnormal value is determined.

[0087] If abnormal values ​​appear in all candidate control positions and the sensor numbers corresponding to the abnormal values ​​are the same, it is determined that the stress sensor corresponding to the same number is faulty.

[0088] Specifically, the malfunction of a stress sensor can be determined by measuring its values. Multiple stress sensors can be numbered, with each sensor corresponding to a different sensor number.

[0089] Under the current candidate control setting, normal stress measurements from multiple stress sensors can be obtained. The average value of these measurements can be calculated. If the difference between any normal stress measurement and this average value is greater than a preset difference, the normal stress measurement is determined to be an anomaly under the current candidate control setting, and the sensor number corresponding to the anomaly is identified. The preset difference can be determined as needed.

[0090] If abnormal values ​​appear at every candidate control position, and the sensor number corresponding to each abnormal value is the same, then the stress sensor corresponding to that sensor number is faulty. In subsequent testing, the measurements from that stress sensor can be excluded to improve measurement accuracy. Alternatively, the stress sensor can be replaced.

[0091] The structural component assembly method provided in this application improves the accuracy of structural component assembly and enhances the stability of structural component assembly performance during long-term service by determining the faulty stress sensor by measuring the normal stress value under each candidate control position.

[0092] In some embodiments, the drive device is dynamically coupled to the movable end of the fastener; the dynamic coupling connection includes at least one of gear connection, belt connection, chain connection and coaxial connection.

[0093] Specifically, the drive unit and the fastener can be connected via power coupling, applying torque to the moving end of the fastener. Power coupling refers to the interconnection of two or more mechanical systems through a common power source. The main types of power coupling connections include:

[0094] (1) Gear connection, that is, power is transmitted through the meshing of gears;

[0095] (2) Belt connection, that is, power is transmitted through the friction of the belt;

[0096] (3) Chain connection, that is, power is transmitted through the chain;

[0097] (4) Coaxial connection, that is, two shafts are connected by a coupling to transmit power.

[0098] The structural component assembly method provided in this application connects the drive device and the fastener through dynamic coupling, thereby applying torque to the fastener and generating normal stress at the contact interface between the first and second structural components, which improves the stability of the structural component assembly performance during long-term service.

[0099] In some embodiments, the driving device is a stepper motor;

[0100] A stepper motor is used to apply rotational torque to the moving end, so that the moving end moves relative to the fixed end.

[0101] Specifically, the drive device can be at least one of pneumatic, hydraulic, and electric actuators. Preferably, the drive device can be a stepper motor. The stepper motor is used to apply rotational torque to the moving end, causing the moving end to move relative to the fixed end.

[0102] Stepper motors have the following advantages:

[0103] (1) It can precisely control the rotation angle and speed, making it very useful in applications that require high precision;

[0104] (2) Stepper motors have a long lifespan and are not prone to failure, and have high reliability;

[0105] (3) Stepper motors only need to control the direction and magnitude of the current, so the control circuit is relatively simple;

[0106] (4) Stepper motors have low noise during operation and are suitable for some application scenarios with high noise requirements;

[0107] (5) Stepper motors can provide high torque when running at low speeds, making them suitable for applications that require high torque.

[0108] (6) Stepper motors can determine their position by controlling the current, so no sensor is needed to detect the position.

Figure 3 As shown, the system includes a controller 250, a drive unit 240, fasteners 230, and multiple stress sensors 260. The dashed lines in the figure represent the power coupling connection.

[0110] The movable end of the fastener 230 is connected to the first end of the first structural member, and the fixed end is connected to the second end of the second structural member; the second end of the first structural member is connected to the first end of the second structural member.

[0111] The stress sensor 260 is disposed between the first structural member and the second structural member to obtain the measured value of the normal stress between the first structural member and the second structural member;

[0112] The drive device 240 is dynamically coupled to the movable end of the fastener 230 and is used to drive the movable end of the fastener 230 to move relative to the fixed end of the fastener 230.

[0114] Specifically, the controller 250, drive unit 240, fastener 230 and multiple stress sensors 260 can be connected by cables or communicate via a wireless network.

[0115] The structural component assembly system provided in this application embodiment can be applied to the assembly of ship structural components, and specifically performs the following methods:

[0116] First, following traditional methods, the optimal normal stress F is evaluated based on the material properties and assembly process requirements of the structural component before assembly. p That is, the target value of normal stress;

[0117] Secondly, based on the m stress sensors deployed at the assembly reference interface (i.e., contact interface) of the structural components, the normal stress formed on the structural components at the assembly reference interface is measured in real time. A set of rotary stepper motors (n step positions) and a controller are deployed at the movable end (assembly bolts) of the fasteners connecting the structural components (including assembly bolts and nuts) to adjust the tightness of the assembly bolts in real time.

[0118] Then, during the assembly process, a data acquisition device is connected to a stress sensor, establishing communication between the data acquisition device and the controller. For each of the n stepper motor settings, m normal stress data points formed on the assembly reference interface of the structural component are measured at each stepper motor setting. The m normal stress data points are then calculated relative to the optimal normal stress F. p If the standard deviation S is the minimum value of the standard deviation S, then the stepper gear corresponding to the minimum value of the standard deviation S is the optimal gear. The optimal gear is set for the rotary stepper motor by the controller.

[0119] Finally, during the service life of the structural components, the previous steps are followed regularly to perform testing and analysis at n different speed levels, and the optimal speed setting is updated based on the analysis results.

[0120] The structural component assembly system provided in this application improves the accuracy of structural component assembly and enhances the stability of structural component assembly performance during long-term service by measuring the normal stress generated between the first and second structural components under various candidate control positions of the drive device, thereby determining the candidate control position closest to the target value of normal stress.
