Abstract
Description
Technical Field
[0001] This application relates to the field of testing technology, and in particular to a method, apparatus, device and storage medium for adjusting the attitude of a testing platform. Background Technology
[0002] In electric drive testing, some tests require controlling the angle of the test piece (DPT) for more effective testing. Currently, the attitude of the test platform can be adjusted using motor systems, screw jack systems, and pneumatic control systems. However, motor systems control the pitch offset of the DPT by rotating the motor shaft, which is unsuitable for heavy DPTs and lacks flexibility, making it difficult to move the DPT quickly. Screw jack systems have slow movement speeds and take a long time to adjust the angle. Pneumatic control systems use changes in air pressure to control the platform's movement, but their output force is relatively small, making it difficult to handle heavy DPTs.

[0054] Traditional solutions utilize motor systems, screw jack systems, and pneumatic control systems to adjust the attitude of the test platform. The motor system, consisting of a base plate and a motor shaft connected to it, controls the pitch and offset of the prototype through shaft rotation. This method is highly dependent on the weight of the prototype; excessive weight can damage the equipment. Furthermore, this solution lacks flexibility and cannot quickly move the prototype. Screw jack platforms rely on screw rotation to control platform lifting and angle adjustment. While adaptable to prototypes of a certain weight, their movement speed is slow, and angle adjustments are time-consuming. Additionally, screw jack systems experience high friction under heavy loads, leading to severe system wear. Pneumatic control systems utilize air pressure changes to control platform movement, typically offering fast response times. However, pneumatic systems have relatively low output force, making them unsuitable for handling heavy prototypes.
[0055] Therefore, traditional methods for adjusting the attitude of test platforms suffer from problems such as poor flexibility, slow adjustment speed, and difficulty in handling heavy test pieces. This application discloses a method, apparatus, device, and storage medium for adjusting the attitude of a test platform, enabling accurate and rapid adjustment of the platform's attitude.
[0056] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0057] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.
[0058] See Figure 1 , Figure 1 This application provides a flowchart illustrating a method for adjusting the attitude of a testing platform, which specifically includes the following steps:
[0059] S101. Determine the attitude adjustment requirements of the hydraulic control platform;
[0060] In this embodiment, the test platform is a hydraulic control platform. Hydraulic columns are installed at the bottom of the platform, and precise control of the platform's attitude is achieved through the extension and retraction of these columns. In this embodiment, the hydraulic control platform has m*n hydraulic columns, where m is the number of hydraulic columns in the horizontal direction and n is the number of hydraulic columns in the vertical direction, and both m and n are greater than or equal to 2. See also... Figure 2 , Figure 2 This is a schematic diagram of the hydraulic column components provided in an embodiment of the present invention. Figure 2 As can be seen, in this embodiment, the hydraulic control platform is equipped with nine hydraulic columns, which are evenly distributed at the four corners and the middle of the rectangle. The number of hydraulic columns m in the horizontal direction of the hydraulic control platform is 3, and the number of hydraulic columns n in the vertical direction is 3.
[0061] See Figure 3 , Figure 3 This is a schematic diagram of the system structure of the hydraulic control platform provided in an embodiment of the present invention. In this embodiment, a single hydraulic column is simplified to a system, such as... Figure 3As shown, these nine hydraulic columns can be simplified into nine systems, where system 1 is the system of hydraulic column 1, system 2 is the system of hydraulic column 2, system 3 is the system of hydraulic column 3, system 4 is the system of hydraulic column 4, system 5 is the system of hydraulic column 5, system 6 is the system of hydraulic column 6, system 7 is the system of hydraulic column 7, system 8 is the system of hydraulic column 8, and system 9 is the system of hydraulic column 9. In this embodiment, the bottom of the hydraulic control platform uses the above nine hydraulic columns. By hydraulically controlling the extension and retraction of each hydraulic column, the platform is controlled to different angles, thus completing the attitude adjustment of the platform.
[0062] The attitude adjustment requirement in this embodiment is a work requirement, that is, the requirement to adjust the test platform to a predetermined angle, such as adjusting the platform to a tilt of 15 degrees forward or backward. This attitude adjustment requirement can be customized according to work requirements and is not specifically limited here.
[0063] S102. Based on the attitude adjustment requirements, determine the first hydraulic input value corresponding to the first hydraulic column and the target parameter value corresponding to each hydraulic column; wherein, the target parameter value is the parameter value when the hydraulic column is adjusted to meet the attitude adjustment requirements, and the target parameter value includes the target pressure value and / or the target hydraulic value;
[0064] S103. Adjust the posture of the first hydraulic column using the first hydraulic input value;
[0065] In this embodiment, when adjusting the posture of each hydraulic column, it is first necessary to determine the initial hydraulic column to be adjusted. In this embodiment, the initial hydraulic column to be adjusted is referred to as the first hydraulic column, such as... Figure 3 As shown, the attitude adjustment requirement is to adjust the platform to a 15-degree forward and backward tilt. At this point, hydraulic columns 1, 4, and 7 can be selected as the first hydraulic columns. That is, when adjusting the attitude of each hydraulic column, the attitude of hydraulic columns 1, 4, and 7 should be adjusted first. The first hydraulic input value is the value at which the first hydraulic columns are adjusted to meet the attitude adjustment requirement. This first hydraulic input value can be understood as the oil inlet volume. By adjusting the oil inlet volume of each hydraulic column, the attitude of each first hydraulic column can be adjusted.
[0066] In this embodiment, the first hydraulic input value needs to be determined based on the attitude adjustment requirements. For example, if the attitude adjustment requirement is to adjust the platform to tilt forward and backward by 15 degrees, see [reference needed]. Figure 3To meet this requirement, the heights of hydraulic columns 1, 4, and 7 need to be increased by ΔH1, while the heights of hydraulic columns 3, 6, and 9 need to be decreased by ΔH2. Then, through calculation, the oil intake volume when hydraulic columns 1, 4, and 7 are increased by ΔH1 is determined, thereby determining the first hydraulic input values for hydraulic columns 1, 4, and 7.
[0067] Furthermore, in this embodiment, the lifting and lowering of the hydraulic columns needs to be gradually increased or decreased during the adjustment process to avoid sudden, large changes that could cause platform instability. Therefore, in this embodiment, the posture of each hydraulic column is gradually adjusted using the target parameter value corresponding to each hydraulic column. The target parameter value is the parameter value used to adjust the hydraulic column to meet the posture adjustment requirements. In this example, the target parameter value can be the target pressure value, the target hydraulic pressure value, or both. That is, this solution can gradually adjust the posture of each hydraulic column based solely on its pressure value, solely on its hydraulic pressure value, or gradually adjust the posture of each hydraulic column based on both its pressure and hydraulic pressure values.
[0068] The target pressure and hydraulic pressure values can be determined based on the attitude adjustment requirements: First, calculate the required adjustment height for each hydraulic cylinder based on the attitude adjustment requirements. Then, calculate the oil inlet volume for each hydraulic cylinder based on this height. Finally, combine the oil inlet volume with the pressure / hydraulic pressure ratio to calculate the target pressure and hydraulic pressure values for each hydraulic cylinder. The target pressure and hydraulic pressure values are related to the load weight on the platform; the greater the load weight, the greater the target pressure and hydraulic pressure values of the hydraulic cylinders, showing a direct proportional relationship.
[0069] It is understandable that the structure of each hydraulic column in the hydraulic control platform is identical; therefore, the structure of a single hydraulic column will be used as an example for explanation. (See also...) Figure 4 , Figure 4 A schematic diagram of the structure of a single hydraulic column provided in an embodiment of the present invention; Figure 4This is a schematic diagram of a single hydraulic cylinder structure drawn using Simulink (a visualization simulation tool). In the diagram: Manual SwitchConstant represents a switch; when the switch is to the down arrow, the hydraulic input value is 0, meaning there is no input. When the switch is to the up arrow, the value input is recorded as the hydraulic input value. Simulink-PS Converter, PS-SimulinkConverter, PS-Simulink Converter1, and PS-Simulink Converter2 represent different converters. ValveActuator represents a valve actuator. Solver Configuration represents the solver configuration. Hydraulic Reference represents the oil tank. He represents the oil pump. 4-Way Directional Valve represents a four-way hydraulic valve. Double-ActingHydraulic Cylinder represents a two-way hydraulic cylinder. Mass represents the load. Translational Damper represents a translational damper. Translational Spring represents a translational spring. Ideal Force Sensor represents an idealized force sensor. Hydraulic Pressure... Seneor represents a hydraulic sensor, Hydraulic represents a flow sensor; Scope, Scope1, and Scope2 represent different oscilloscopes used to view simulation results.
[0070] pass Figure 4 As can be seen, the main body of the hydraulic column uses a two-way hydraulic cylinder and a four-way hydraulic valve. The four-way hydraulic valve is used to control the flow direction of the hydraulic fluid, ensuring that the hydraulic cylinder extends and retracts in the correct direction. The two-way hydraulic cylinder can convert the energy stored in the hydraulic system into mechanical energy, and control the displacement of the platform by extending and retracting the cylinder body. At the same time, a switch is designed to control the valve's conduction. By controlling the opening and closing of the valve, the hydraulic cylinder's action can be quickly responded to and automatically adjusted according to different posture adjustment requirements.
[0071] S104. During the attitude adjustment process of the first hydraulic column, the second hydraulic column to be adjusted and its corresponding second hydraulic input value are determined according to the target parameter value and real-time parameter value of each hydraulic column. The attitude of the second hydraulic column is adjusted using the second hydraulic input value until the hydraulic control platform meets the attitude adjustment requirements.
[0072] In this embodiment, during the attitude adjustment of the first hydraulic column, a dual feedback mechanism of force feedback and / or hydraulic feedback can be used to adjust the attitude of different hydraulic columns, improving the system's anti-interference capability and adjustment accuracy. In this embodiment, the hydraulic column whose attitude needs adjustment during the feedback adjustment process is referred to as the second hydraulic column, and the hydraulic input value corresponding to the second hydraulic column is referred to as the second hydraulic input value. The attitude of the second hydraulic column is adjusted using the second hydraulic input value until the hydraulic control platform meets the attitude adjustment requirements. It should be noted that the determination process of the second hydraulic column and the second hydraulic input value is continuously changing throughout the adjustment process. Whenever an adjustment is detected for a particular hydraulic column, the hydraulic column to be adjusted is designated as the second hydraulic column, and the hydraulic input value is designated as the second hydraulic input value for adjustment, until the entire hydraulic control platform meets the attitude adjustment requirements, and the height position of the hydraulic columns no longer needs to be adjusted.
[0073] In this embodiment, the existence of a second hydraulic column to be adjusted is determined by the target parameter value and real-time parameter value of each hydraulic column. The target parameter value is the parameter value required to adjust the hydraulic column to meet the posture adjustment requirements. The target parameter value can be a target pressure value and / or a target hydraulic value. The real-time parameter value is the current real-time pressure value and / or real-time hydraulic value of the hydraulic column. If this solution only uses pressure value for feedback adjustment, then the target parameter value is the target pressure value, and the real-time parameter value is the real-time pressure value. If this solution only uses hydraulic value for feedback adjustment, then the target parameter value is the target hydraulic value, and the real-time parameter value is the real-time hydraulic value. If this solution uses both pressure value and hydraulic value for feedback adjustment, then the target parameter value is the target pressure value and the target hydraulic value, and the real-time parameter value is the real-time pressure value and the real-time hydraulic value. The posture of each hydraulic column is gradually adjusted by combining the pressure value and the hydraulic value.
[0074] Specifically, if the real-time parameter values of the hydraulic cylinders are the same as the target parameter values, it means that the posture of the hydraulic cylinders does not need to be adjusted. If the real-time parameter values are different from the target parameter values, it means that the posture of the hydraulic cylinders needs to be further adjusted. At this time, it is necessary to calculate a second hydraulic input value based on the ratio between the oil supply and the parameter values, so that the error value of the parameter values is fed back to the oil supply control. Then, by correcting the oil supply, the parameter values are adjusted. For example, if the real-time pressure value of the hydraulic cylinder is greater than the target pressure value, the pressure value needs to be reduced. At this time, it is necessary to determine the second hydraulic input value that needs to be adjusted to reduce the pressure value based on the ratio between the oil supply and the pressure. Therefore, after adjusting the oil supply through the second hydraulic input value, the real-time pressure value of the hydraulic cylinder can be adjusted until the detected real-time pressure value is the target pressure value. Through continuous feedback adjustment, the real-time parameter values of each hydraulic cylinder can be made the same as the target parameter values. At this time, it can be determined that the current posture of the platform meets the posture adjustment requirements. It should be noted that if the pressure generated by the hydraulic cylinder is too high, the force can be reduced by lowering the height of the hydraulic cylinder; if the pressure generated by the hydraulic cylinder is too low, the force can be increased by raising the height of the hydraulic cylinder.
[0075] For example: If the posture adjustment requirement is to adjust the platform to tilt forward and backward by 15 degrees, then it is necessary to raise the height of hydraulic column 1, hydraulic column 4 and hydraulic column 7 by ΔH1, and raise the height of hydraulic column 3, hydraulic column 6 and hydraulic column 9 by ΔH2. Determine the first hydraulic input value for raising hydraulic column 1, hydraulic column 4 and hydraulic column 7, and adjust the height of hydraulic column 1, hydraulic column 4 and hydraulic column 7 respectively according to the first hydraulic input value. During this adjustment process, to ensure platform stability, it is necessary to determine the second hydraulic input values for hydraulic columns 3, 6, and 9. The heights of hydraulic columns 3, 6, and 9 are then gradually adjusted based on these second hydraulic input values. Furthermore, if hydraulic columns 1, 4, and 7 are to rise to the same height, but a significant difference in real-time pressure values is detected between hydraulic columns 1 and 4, it indicates that their rising speeds are different. In this case, the hydraulic input values of the hydraulic columns can be adjusted to reduce the difference in real-time pressure values between hydraulic columns 1 and 4, thus ensuring the stability of the hydraulic columns during the adjustment process.
[0076] In summary, the test platform in this embodiment is a hydraulic control platform. The platform's posture is adjusted by controlling the extension and retraction of the hydraulic cylinders. This hydraulic control method has a fast response speed and can complete the posture adjustment of the platform in a short time. Furthermore, the hydraulic control method can handle larger loads and is suitable for larger and heavier test samples, thus broadening the application range of the test platform. Moreover, when adjusting the posture of the test platform, this application can adjust the posture of each hydraulic cylinder in real time based on the pressure and hydraulic value of each hydraulic cylinder, thereby improving the posture adjustment speed and accuracy, ensuring the stability between different hydraulic cylinders, and avoiding the test platform from becoming unbalanced due to local adjustments.
[0077] See Figure 5 , Figure 5 A schematic flowchart of another attitude adjustment method for a testing platform provided in this application embodiment is shown. The method specifically includes the following steps:
[0078] S201. Determine the attitude adjustment requirements of the hydraulic control platform;
[0079] S202. Determine the transverse hydraulic column assembly and the longitudinal hydraulic column assembly in the hydraulic control platform;
[0080] S203. Based on the posture adjustment requirements, determine the first hydraulic column group for initial adjustment from the horizontal hydraulic column group and the longitudinal hydraulic column group.
[0081] S204. Based on the attitude adjustment requirements, determine the first hydraulic input value corresponding to each first hydraulic column in the first hydraulic column group;
[0082] S205. Determine the target parameter values corresponding to each hydraulic column according to the attitude adjustment requirements; wherein, the target parameter values are the parameter values that will adjust the hydraulic column to meet the attitude adjustment requirements, and the target parameter values include target pressure values and / or target hydraulic values.
[0083] S206. Adjust the posture of the first hydraulic column using the first hydraulic input value;
[0084] S207. During the attitude adjustment process of the first hydraulic column, the attitude adjustment mode of the hydraulic control platform is determined, and at least two target hydraulic columns are determined according to the attitude adjustment mode; the attitude adjustment mode includes intra-group adjustment mode and inter-group adjustment mode.
[0085] S208. Determine the second hydraulic column to be adjusted and the corresponding second hydraulic input value based on the target parameter values and real-time parameter values of at least two target hydraulic columns.
[0086] S209. Adjust the posture of the second hydraulic column using the second hydraulic input value until the hydraulic control platform meets the posture adjustment requirements.
[0087] In this embodiment, when determining the first hydraulic input value corresponding to the first hydraulic column based on the attitude adjustment requirements, a certain group of hydraulic columns can be used as the first hydraulic column for adjustment, thereby improving the attitude adjustment speed and accuracy. See also... Figure 3 The system includes nine hydraulic columns. In this embodiment, the nine hydraulic columns can be divided into six groups: three groups of horizontal hydraulic columns and three groups of vertical hydraulic columns. The horizontal hydraulic column groups are used to control the platform's attitude adjustment in the left-right direction, and the vertical hydraulic column groups are used to control the platform's attitude adjustment in the front-back direction. Specifically, in this embodiment, the first group of horizontal hydraulic columns includes hydraulic columns 1, 4, and 7; the second group includes hydraulic columns 2, 5, and 8; and the third group includes hydraulic columns 3, 6, and 9. Similarly, the first group of vertical hydraulic columns includes hydraulic columns 1, 2, and 3; the second group includes hydraulic columns 4, 5, and 6; and the third group includes hydraulic columns 7, 8, and 9.
[0088] In this embodiment, when determining the first hydraulic column group for initial adjustment, any group can be selected from the horizontal hydraulic column group and the longitudinal hydraulic column group as the first hydraulic column group for initial adjustment according to the posture adjustment requirements. The hydraulic columns in the first hydraulic column group are the first hydraulic column group, and the hydraulic input value of each first hydraulic column is the first hydraulic input value. For example, if the posture adjustment requirement is to adjust the platform to tilt forward and backward by 15 degrees, then the height of hydraulic columns 1, 4, and 7 in the first group of horizontal hydraulic columns needs to be increased by ΔH1, and the height of hydraulic columns 3, 6, and 9 in the third group of horizontal hydraulic columns needs to be increased by ΔH2. The height of hydraulic columns 2, 5, and 8 in the second group of horizontal hydraulic columns remains unchanged. Therefore, in this embodiment, the first group of horizontal hydraulic columns can be used as the first hydraulic column group for initial adjustment, and hydraulic columns 1, 4, and 7 in the first group of horizontal hydraulic columns are all first hydraulic columns. The corresponding first hydraulic input value is calculated based on the height value to be adjusted for each hydraulic column. It should be noted that in this embodiment, the horizontal combination is given priority. If the longitudinal combination is given priority, the first group of longitudinal hydraulic columns can also be used as the first hydraulic column group for initial adjustment; this is not specifically limited here.
[0089] Furthermore, when determining the second hydraulic column to be adjusted and its corresponding second hydraulic input value, this solution can be based on the attitude adjustment mode of the hydraulic control platform. This attitude adjustment mode includes intra-group adjustment mode and inter-group adjustment mode. In this solution, "group" refers to the transverse hydraulic column group and the longitudinal hydraulic column group. Moreover, to more smoothly adjust the attitude of each hydraulic column, this application needs to determine at least two target hydraulic columns based on the attitude adjustment mode. Based on the real-time parameter values and target parameter values of at least two target hydraulic columns, the second hydraulic column whose attitude needs adjustment and its corresponding second hydraulic input value are determined. The second hydraulic column can be any one or more of the target hydraulic columns. For example, if the selected target hydraulic columns include hydraulic column 1 and hydraulic column 2, then the second hydraulic column can be hydraulic column 1, hydraulic column 2, or both hydraulic columns 1 and 2, and can be set according to the actual situation.
[0090] If the attitude adjustment mode is an intra-group adjustment mode, then at least two target hydraulic columns are selected from each hydraulic column in the transverse hydraulic column group, or at least two target hydraulic columns are selected from each hydraulic column in the longitudinal hydraulic column group. For example, hydraulic columns 1 and 4 are selected as target hydraulic columns from the first transverse hydraulic column group, and hydraulic column 1 is selected as the second hydraulic column to be adjusted. Then, the attitude of hydraulic column 1 is adjusted according to the real-time parameter values and target parameter values of hydraulic columns 1 and 4. If the attitude adjustment mode is an inter-group adjustment mode, then at least two target hydraulic columns are selected from the two transverse hydraulic column groups. Two target hydraulic columns can be selected, with the same number of target hydraulic columns selected in each transverse hydraulic column group; or, at least two target hydraulic columns can be selected from two longitudinal hydraulic column groups, with the same number of target hydraulic columns selected in each longitudinal hydraulic column group. For example, if hydraulic column No. 1 is selected as the target hydraulic column from the first transverse hydraulic column group, hydraulic column No. 2 is selected as the target hydraulic column from the second transverse hydraulic column group, and hydraulic column No. 1 is selected as the second hydraulic column to be adjusted, then the attitude of hydraulic column No. 1 is adjusted according to the real-time parameter values and target parameter values of hydraulic columns No. 1 and No. 2.
[0091] Specifically, when determining the second hydraulic input value corresponding to the second hydraulic column to be adjusted, this application can use various methods, which are not specifically limited here. For example, if the target pressure values of hydraulic columns 1 and 4 are the same, but the real-time pressure value of hydraulic column 1 is less than that of hydraulic column 4, and there is a pressure difference between hydraulic columns 1 and 4, then the real-time pressure value of hydraulic column 1 can be increased by setting the second hydraulic input value of hydraulic column 1, or the real-time pressure value of hydraulic column 4 can be decreased by setting the second hydraulic input value of hydraulic column 4. Alternatively, the second hydraulic input values of hydraulic columns 1 and 4 can be set simultaneously, allowing for the simultaneous execution of both steps to achieve rapid attitude adjustment.
[0092] In summary, this application divides the hydraulic control platform into a horizontal hydraulic column group and a vertical hydraulic column group. When adjusting the platform's posture, it first determines one set of hydraulic columns from the horizontal and vertical hydraulic column groups for initial adjustment, achieving rapid adjustment of the hydraulic columns. Furthermore, this method of first adjusting the first hydraulic column group and then adjusting the posture of other hydraulic columns based on the real-time parameter values of each hydraulic column ensures the balance and stability of the platform during posture adjustment. Moreover, when adjusting the posture, this solution can determine the second hydraulic column to be adjusted according to the adjustment mode, thereby adjusting the posture of the hydraulic columns based on the parameter values of the hydraulic columns within and between groups, achieving precise control of the hydraulic columns.
[0093] Based on the above embodiments, in this embodiment, if the attitude adjustment mode is an intra-group adjustment mode, then this application determines at least two target hydraulic columns according to the attitude adjustment mode, and the process of determining the second hydraulic column to be adjusted and the corresponding second hydraulic input value according to the target parameter values and real-time parameter values of the at least two target hydraulic columns specifically includes:
[0094] The first hydraulic column group is determined from either the transverse hydraulic column group or the longitudinal hydraulic column group;
[0095] Select any two hydraulic columns from the first hydraulic column group as the first target hydraulic columns;
[0096] Determine the real-time parameter values for each first target hydraulic column;
[0097] Select at least one second hydraulic column to be adjusted from the first target hydraulic column;
[0098] The second hydraulic input value of the second hydraulic column is determined based on the target parameter value and real-time parameter value of each first target hydraulic column.
[0099] Understandably, if the attitude adjustment mode is set to intra-group adjustment, then intra-group attitude adjustment is required for either the transverse or longitudinal hydraulic column group. The transverse hydraulic column group controls the platform's attitude adjustment in the left-right direction. In this group, the interaction between the hydraulic columns is primarily controlled through force and hydraulic feedback. When the platform undergoes rapid left-right tilt adjustments, the hydraulic columns can be fine-tuned in advance to prevent drastic attitude changes, improving the smoothness and comfort of platform adjustment. The longitudinal hydraulic column group is mainly used for the platform's attitude adjustment in the forward-backward direction. In this group, each hydraulic column is precisely controlled through a combination of force and hydraulic feedback, allowing the system to adjust the attitude of each column in real time according to different loads and attitude adjustment requirements. When the force difference between the hydraulic columns is large, the system automatically increases the response force of the control feedback to shorten the adjustment time and reduce errors.
[0100] Specifically, during feedback adjustment, the first step is to determine the first hydraulic column group to be adjusted from either the horizontal or vertical hydraulic column group. Then, any two hydraulic columns from this first hydraulic column group are selected as the first target hydraulic columns. The number of these first target hydraulic columns is two. The second hydraulic column to be adjusted and its second hydraulic input value are determined by comparing the real-time parameter values of the two first target hydraulic columns. The second hydraulic column to be adjusted is selected from the two first target hydraulic columns; it can be any one of the first target hydraulic columns or both of them. Finally, the second hydraulic input value of the second hydraulic column is determined based on the target parameter values and real-time parameter values of each first target hydraulic column.
[0101] For example, if there are three sets of transverse hydraulic cylinders and three sets of longitudinal hydraulic cylinders, all six sets of hydraulic cylinders can be used as the first hydraulic cylinders to be adjusted. Alternatively, any one or more sets of hydraulic cylinders can be selected as the first hydraulic cylinders to be adjusted. In this embodiment, only the first set of transverse hydraulic cylinders is used as an example. If the first set of transverse hydraulic cylinders includes hydraulic cylinders 1, 4, and 7, then hydraulic cylinders 1 and 4 are selected as the first target hydraulic cylinders. If the target pressure value of hydraulic cylinder 1 is 10, and the target pressure value of hydraulic cylinder 4 is also 10, and hydraulic cylinders 1 and 4 are currently adjusting their posture according to the first hydraulic input value, but the real-time pressure value of hydraulic cylinder 1 is... The real-time pressure value of hydraulic column 1 is 5, while the real-time pressure value of hydraulic column 4 is 3. It can be seen that the target pressure values of hydraulic columns 1 and 4 are the same, both being 10. In order to ensure the balance of the platform, the real-time pressure values of hydraulic columns 1 and 4 should also be the same. However, the real-time pressure value of hydraulic column 1 should be higher than that of hydraulic column 4. At this time, hydraulic column 4 can be used as the second hydraulic column to be adjusted. Since the difference between the real-time pressure values of hydraulic columns 1 and 4 is 2, the second hydraulic input value corresponding to increasing the pressure value of hydraulic column 4 by 2 is calculated. In order to adjust the posture of hydraulic column 4 according to the second hydraulic input value, so that the real-time pressure value of hydraulic column 4 is the same as that of hydraulic column 1, thereby improving the stability of the platform.
[0102] It should be noted that when determining the second hydraulic input value of the second hydraulic column to be adjusted, this application can calculate it based on the ratio of the target parameter values of each first target hydraulic column. For example, if the target parameter value of hydraulic column 1 is 10 and the target parameter value of hydraulic column 4 is also 10, the ratio of the target parameter values is 1:1. The difference between the real-time pressure values of hydraulic columns 1 and 4 is calculated to be 2. This difference can be divided into two parts: by dividing the difference by 2, adjusting the second hydraulic input value of hydraulic column 1 reduces its real-time parameter value by 1, and adjusting the second hydraulic input value of hydraulic column 4 increases its real-time parameter value by 1. This achieves a balance between hydraulic columns 1 and 4. Furthermore, since the target parameter values and real-time parameter values in this embodiment can be not only pressure values but also hydraulic values, this application can control the adjustment process through a dual feedback mechanism of pressure and hydraulic pressure to ensure stable operation of the platform at different angles.
[0103] In summary, this application significantly enhances the system's anti-interference capability through the combined pressure of the hydraulic column's extension and retraction, and the dual feedback mechanism of hydraulic pressure. This enables high-precision control of the platform angle, ensuring stable posture even in complex testing environments. Furthermore, by dividing the hydraulic control platform into longitudinal and lateral configurations, this application allows for flexible and rapid adjustment of the platform's forward / backward and left / right postures, adapting to different testing requirements and greatly improving testing efficiency.
[0104] Based on the above embodiments, in this embodiment, if the attitude adjustment mode is an inter-group adjustment mode, then this application determines at least two target hydraulic columns according to the attitude adjustment mode, and the process of determining the second hydraulic column to be adjusted and the corresponding second hydraulic input value according to the target parameter values and real-time parameter values of the at least two target hydraulic columns specifically includes:
[0105] The second and third hydraulic column groups are determined from either the transverse hydraulic column group or the longitudinal hydraulic column group;
[0106] At least one hydraulic column is selected from the second hydraulic column group as the second target hydraulic column, and at least one hydraulic column is selected from the third hydraulic column group as the third target hydraulic column; wherein the number of second target hydraulic columns is the same as the number of third target hydraulic columns.
[0107] Determine the real-time parameter values for each second target hydraulic column and each third target hydraulic column;
[0108] Select at least one second hydraulic column to be adjusted from the second target hydraulic column and the third target hydraulic column;
[0109] The second hydraulic input value of the second hydraulic column is determined based on the target parameter values and real-time parameter values of each second target hydraulic column and the third target hydraulic column.
[0110] In this embodiment, if the attitude adjustment mode is an inter-group adjustment mode, the attitude of each hydraulic column needs to be adjusted through real-time parameter value feedback between different groups. Here, "different groups" in this embodiment refers to different transverse hydraulic column groups or different longitudinal hydraulic column groups. Therefore, the second and third hydraulic column groups selected in this embodiment are chosen from either the transverse or longitudinal hydraulic column groups. After determining the second and third hydraulic column groups, at least one hydraulic column needs to be selected from the second hydraulic column group as the second target hydraulic column, and at least one hydraulic column needs to be selected from the third hydraulic column group as the third target hydraulic column. Then, based on the target parameter values and real-time parameter values of the second and third target hydraulic columns, the second hydraulic input value of the second hydraulic column is determined; this second hydraulic column is the hydraulic column to be adjusted among the second and third target hydraulic columns.
[0111] It should be noted that this application achieves the attitude adjustment of each group of hydraulic cylinders through an inter-group adjustment mode. The hydraulic input value of the first group of hydraulic cylinders is used as a reference to determine the hydraulic input values of the other groups. For example, if a certain slope is required on the platform, the required slope needs to be converted into the hydraulic input value of the first group of hydraulic cylinders based on the actual situation, and then the attitude of the first group of hydraulic cylinders is adjusted. At this time, the real-time parameter value of the first group of hydraulic cylinders has changed. After detecting this change, the real-time parameter value is fed back to the second group of hydraulic cylinders. Upon receiving the feedback, the second group of hydraulic cylinders adjusts its hydraulic input according to a preset control strategy to generate a real-time parameter value that matches the real-time parameters of the first group of hydraulic cylinders.
[0112] For example, a horizontal hydraulic column assembly includes a first horizontal hydraulic column assembly, a second horizontal hydraulic column assembly, and a third horizontal hydraulic column assembly. In this case, the first horizontal hydraulic column assembly can be selected as the second hydraulic column assembly, and the second horizontal hydraulic column assembly can be selected as the third hydraulic column assembly. The first horizontal hydraulic column assembly includes hydraulic columns 1, 4, and 7; the second horizontal hydraulic column assembly includes hydraulic columns 2, 5, and 8. All three hydraulic columns in the first horizontal hydraulic column assembly are selected as the second target hydraulic columns, and all three hydraulic columns in the second horizontal hydraulic column assembly are selected as the third target hydraulic columns. If the target parameter values of hydraulic columns 1, 4, and 7 are all 10, while the target parameter values of hydraulic columns 2, 5, and 8 are all 5, and the real-time parameter values of hydraulic columns 1, 4, and 7 are 2, while the target parameter values of hydraulic columns 2, 5, and 8 are all 0, this indicates that the attitude of each hydraulic column in the first group of transverse hydraulic columns has been adjusted first. At this point, the attitude of the second group of transverse hydraulic columns can be adjusted according to the ratio of the target parameter values of the first group of transverse hydraulic columns to those of the second group of transverse hydraulic columns.
[0113] Specifically, since the total target parameter value of the first group of horizontal hydraulic columns is 30, while the total target parameter value of the second group of horizontal hydraulic columns is 15, the ratio is 2:1. Furthermore, the real-time parameter values of hydraulic columns 1, 4, and 7 are 2. Therefore, a second hydraulic input value needs to be set to adjust the real-time parameter values of hydraulic columns 2, 5, and 8 to 1. During the adjustment of the posture of hydraulic columns 1, 4, and 7, the posture of hydraulic columns 2, 5, and 8 can be adjusted in real-time based on the continuous changes in their real-time parameter values. This ensures that the ratio of the real-time parameter values of hydraulic columns 1, 4, and 7 to those of hydraulic columns 2, 5, and 8 remains at 2:1, thereby allowing each hydraulic column to be stably and accurately adjusted to meet the posture adjustment requirements.
[0114] This inter-group adjustment mode allows for automatic adjustment between different groups of hydraulic columns based on pressure and hydraulic feedback, ensuring balance among them and preventing platform imbalance caused by localized adjustments. Furthermore, this mode enables coordinated work between different groups of hydraulic columns, preventing drastic changes in platform posture and ensuring overall platform stability and accuracy of posture adjustments. This coordinated adjustment method significantly improves the response speed and stability of platform posture adjustments. For example, when the first group of hydraulic columns adjusts the platform's forward or backward tilt, the system automatically feeds back the adjustment information to the second group of hydraulic columns, without waiting for the first group to complete its adjustment before adjusting the second group, thus ensuring that the platform does not become unbalanced due to adjustments made by a single system.
[0115] For ease of understanding, a specific embodiment is provided here to illustrate the process of the attitude adjustment method. This process includes the following three parts:
[0116] I. Initialization Phase:
[0117] During the initialization phase, first ensure that all hydraulic columns are in their initial state, i.e., at the same height or at a preset reference position; check the pressure, flow rate, and other parameters of the hydraulic system to ensure normal operation. Determine the platform's tilt direction, the hydraulic column's lifting direction, and the lifting height based on the posture adjustment requirements.
[0118] For example, a hydraulic control platform includes nine hydraulic columns arranged in a 3x3 configuration. The required attitude adjustment is as follows: to tilt the platform forward and backward by 15 degrees, the first group of hydraulic columns (e.g., columns 1, 4, and 7) needs to be raised, the third group (e.g., columns 3, 6, and 9) needs to be lowered, and the second group (e.g., columns 2, 5, and 8) remains unchanged. Assuming the initial height of the hydraulic columns is H0, when the platform needs to be tilted forward and backward by 15 degrees, the first group of hydraulic columns needs to be raised by ΔH1, and the third group needs to be lowered by ΔH2. Different heights correspond to different hydraulic input values, different target pressure values, and different target hydraulic values.
[0119] II. Group Control:
[0120] First, attitude control is performed based on the hydraulic input value of the first set of hydraulic cylinders. While adjusting the first set of hydraulic cylinders, the hydraulic input value of the third set of hydraulic cylinders is determined in real time based on the target parameter value and the real-time parameter value, according to the inter-group adjustment mode. The attitude of the third set of hydraulic cylinders is then adjusted to maintain the stability and accuracy of the platform's attitude. It should be noted that since the height of the second set of hydraulic cylinders does not need to be adjusted, its hydraulic input value does not need to be adjusted. However, if necessary, the hydraulic input value of the second set of hydraulic cylinders can be adjusted as required to achieve more complex attitude adjustments.
[0121] III. Gradual Adjustment:
[0122] The above adjustment process requires not only inter-group adjustment mode but also intra-group adjustment mode. Intra-group adjustment mode allows for gradual increase or decrease of the hydraulic column's lifting or lowering amount based on the target and real-time parameter values of different hydraulic columns within the group, preventing sudden, large changes that could lead to platform instability. For example, if the pressure value generated by a certain hydraulic column differs significantly from that of other hydraulic columns, adjusting the lifting or lowering amount of that hydraulic column can help maintain balance with the others.
[0123] See Figure 6aThis is a schematic diagram of an overall system structure provided by an embodiment of the present invention. Figure 6a As can be seen, the hydraulic control platform in this embodiment includes a simplified nine-hydraulic-column system, namely: system1, system2, system3...system9. The input on the left side of the figure is used to input the corresponding hydraulic input value to the hydraulic column system to be adjusted. The pressure value and hydraulic value of each hydraulic column are obtained through the sensor group of each hydraulic column. The posture of each hydraulic column is adjusted through the real-time feedback of the pressure value and hydraulic value.
[0124] See Figure 6b This is a schematic diagram of a longitudinal hydraulic column assembly posture adjustment structure provided in an embodiment of this application. In this embodiment, the posture adjustment process of the longitudinal hydraulic column assembly composed of system1, system2, and system3 is described as an example. Figure 6b As can be seen, each hydraulic column system measures pressure values using a force sensor and hydraulic pressure values using a hydraulic sensor. The specific meanings of each feedback loop in the diagram are as follows:
[0125] loop1_2P1: Indicates that system1 and system2 use hydraulic value as the control standard for feedback control of system1; loop1_2F1: Indicates that system1 and system2 use pressure value as the control standard for feedback control of system1; loop1_2F2: Indicates that system1 and system2 use pressure value as the control standard for feedback control of system2; loop1_2P2: Indicates that system1 and system2 use hydraulic value as the control standard for feedback control of system2; loop2_3F2: Indicates that system2 and system3 use pressure value as the control standard for feedback control of system2. loop2_3P2: indicates that system2 and system3 use hydraulic values as the control standard for feedback control of system2; loop2_3F3: indicates that system2 and system3 use pressure values as the control standard for feedback control of system3; loop2_3P3: indicates that system2 and system3 use hydraulic values as the control standard for feedback control of system3; loop1_3F3: indicates that system1 and system3 use pressure values as the control standard for feedback control of system3; loop1_3P3: indicates that system1 and system3 use hydraulic values as the control standard for feedback control of system3.
[0126] When each feedback loop performs feedback control on the hydraulic column system to be adjusted, it can determine the hydraulic input value of the hydraulic column system to be adjusted based on the difference in pressure / hydraulic value between the two hydraulic column systems. The adjustment input module adjusts the oil supply of the hydraulic column system according to the hydraulic input value. During adjustment, the adjustment is achieved gradually through the corresponding flow sensor or pressure controller to avoid sudden large changes that could cause platform instability.
[0127] For example, if the posture adjustment requirements of the hydraulic control platform determine that System1 and System2 need to be at the same height, then the target pressure values of System1 and System2 should be the same. If the real-time pressure value of System1 is detected to be different from that of System2, then the hydraulic input value of System1 is adjusted through the feedback loop Loop1_2F1 according to the real-time pressure values of System1 and System2, so that the real-time pressure values of System1 and System2 are the same. In this way, the mechanical error between different hydraulic control systems can be fed back to the oil quantity control, and the system balance can be achieved by correcting the oil supply.
[0128] In summary, this solution utilizes a hydraulic control platform built on Simulink, employing multiple hydraulic cylinders to achieve precise control of the platform's attitude by controlling the extension and retraction of each cylinder. In this solution, the hydraulic cylinders are combined longitudinally and laterally to achieve dual control in both intra-group and inter-group adjustment modes. In different modes, the hydraulic cylinder flow rate can be automatically adjusted not only based on pressure feedback but also through hydraulic feedback, enhancing the system's anti-interference capability and adjustment accuracy, and ensuring the response speed and stability of attitude adjustment.
