[0043] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] Reference Figure 1 , Figure 1 This is a schematic structural diagram of a vehicle thrust rod force analysis device in the hardware operating environment involved in an embodiment of the present invention.

The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) or a stable non-volatile memory (NVM), such as a disk storage. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0046] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the vehicle thrust rod force analysis device, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0047] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and a vehicle thrust rod force analysis program.

[0048] exist Figure 1 In the vehicle thrust rod force analysis device shown, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the vehicle thrust rod force analysis device of the present invention can be set in the vehicle thrust rod force analysis device. The vehicle thrust rod force analysis device calls the vehicle thrust rod force analysis program stored in the memory 1005 through the processor 1001 and executes the vehicle thrust rod force analysis method provided by the embodiment of the present invention.

[0049] The embodiment of the present invention provides a vehicle thrust rod force analysis method, referring to Figure 2 , Figure 2 The figure is a flow chart of a first embodiment of a vehicle thrust rod force analysis method according to the present invention.

[0050] In this embodiment, the vehicle thrust rod force analysis method includes the following steps:

[0051] Step S10: performing a force test on a target thrust rod in a target vehicle, and obtaining axial force information and cable displacement information of the target thrust rod during the force test.

[0052] It should be understood that the execution subject of the method of this embodiment can be a vehicle thrust rod force analysis device with data processing, network communication and program running functions, such as a computer, or other devices or equipment that can achieve the same or similar functions. The above-mentioned vehicle thrust rod force analysis device (hereinafter referred to as the force analysis device) is used as an example for illustration.

[0053] It should be noted that before the force analysis equipment performs a force test on the target thrust rod, at least one strain gauge can be installed on the target thrust rod, and then the stress-strain relationship of each strain gauge is calibrated, that is, the load corresponding to the unit strain gauge is determined. Only then can the corresponding measured load be converted based on the strain test results.

[0054] Before calibrating each strain gauge, the force analysis equipment fixes one end of the target thrust rod and applies three-dimensional tension or torque to the other end. After the application, the stress-strain relationship of each strain gauge is calibrated. After the calibration is completed, the calibrated target thrust rod is installed on the target vehicle. The assembled target thrust rod is relative to the test sensor that transmits force between the axle and the frame of the target vehicle. The target thrust rod is connected to the strain testing instrument to perform a force test.

[0055] The axial force information of the target thrust rod can be measured relatively accurately using the above method. However, force has a direction, and the loading direction of the load also needs to be considered when analyzing the forces acting on the relevant supports. In addition, when the axle moves relative to the frame, the axle will drive the thrust rod to move, causing the angle of the target thrust rod to change. Therefore, the force analysis of the target thrust rod can be performed by combining the axial force information and the cable displacement information.

[0056] Step S20: performing directional decomposition on the axial force information and the cable displacement information according to the coordinate system information corresponding to the target vehicle, and obtaining downward load information of the target thrust rod in all directions.

[0057] It should be noted that since it is impossible to effectively and directly obtain the angle information of the target thrust rod, the force analysis equipment of this embodiment can install a wire sensor at the end of the target thrust rod and the frame, and the other end of the wire sensor is installed on the corresponding axle directly below the frame. Then, by obtaining the relative displacement information of each preset measuring point on the target vehicle during the force test, refer to the following formula 1 to calculate the angle information of the target thrust rod during the force test based on the relative displacement, where A is the angle information of the target thrust rod relative to the axle, L1 is the relative displacement information between each preset measuring point, A0 is the initial angle of the target thrust rod relative to the axle when static, and L2 is the distance between the two ends of the target thrust rod.

[0058]

[0059] It should be understood that in order to improve the efficiency of force analysis, the force analysis equipment of this embodiment determines the angle information of the target thrust rod relative to the axle based on the wire displacement information, and directional decomposes the axial force information and the angle information according to the coordinate system information corresponding to the target vehicle. The axial force information and the angle information are decomposed according to the Y-axis direction and the Z-axis direction of the target vehicle, and two sets of data are obtained in which the magnitude of the force changes with time but the direction of the force remains unchanged, thereby facilitating analysis and obtaining the load information of the target thrust rod in all directions.

[0060] Furthermore, in order to improve the efficiency of force analysis, the above step S20 may include:

[0061] Determining angle information of the target thrust rod during the force test according to the wire displacement information;

[0062] The axial force information and the angle information are directionally decomposed according to the coordinate system information corresponding to the target vehicle to obtain downward load information of the target thrust rod in all directions.

[0063] It should be noted that the angle information may be information about the angle change of the target thrust rod relative to the axle during the force test. Refer to the following formula 2, which is a calculation formula for the angle change information of the target thrust rod relative to the axle during the force test. Here, ∠A is the angle change information, ΔL is the relative displacement variable between preset measuring points on the target vehicle, ∠A0 is the initial angle of the target thrust rod relative to the axle in a static state, and L is the distance between the two ends of the target thrust rod.

[0064]

[0065] Furthermore, in order to accurately obtain the angle information of the target thrust rod during the force test, the above-mentioned determination of the angle information of the target thrust rod during the force test based on the wire displacement information may include:

[0066] Obtaining relative displacement information of preset measuring points in the target vehicle during the force test, and structural information of the target thrust rod;

[0067] Angle information of the target thrust rod during the force test is determined according to the relative displacement information and the structural information.

[0068] It should be noted that the preset measuring points may be measuring points pre-set on the target vehicle by the force analysis equipment, for example, the preset measuring points may be measuring points on the vehicle frame or on the axle. The aforementioned structural information may be information related to the shaft structure of the target thrust rod, for example, the structural information may include information such as the distance between the ends of the shaft of the target thrust rod and the shaft diameter of the target thrust rod.

[0069] Step S30: performing a force analysis on the target thrust rod based on the load information.

[0070] It should be noted that the load information may be information related to force analysis load data of the target thrust rod and components surrounding the target thrust rod.

[0071] This embodiment performs a force test on a target thrust rod in a target vehicle, obtains axial force information and cable displacement information of the target thrust rod during the force test, directionally decomposes the axial force information and the cable displacement information according to coordinate system information corresponding to the target vehicle, obtains load information of the target thrust rod in all directions, and performs a force analysis on the target thrust rod based on the load information. Since the present invention directionally decomposes the axial force information and the cable displacement information of the target thrust rod during the force test according to the coordinate system information corresponding to the target vehicle, the efficiency of the force analysis is improved, and the force analysis of the target thrust rod is performed based on the load information of the target thrust rod in all directions, thereby improving the accuracy of the thrust rod force analysis, and effectively avoiding the problem of large force analysis errors caused by single data analysis.

[0072] refer to Figure 3 , Figure 3 This is a flow chart of a second embodiment of a vehicle thrust rod force analysis method according to the present invention.

[0073] Based on the above first embodiment, in this embodiment, step S30 includes:

[0074] Step S31: obtaining torque information of the target thrust rod during the force test;

[0075] Step S32: performing force analysis on the target thrust rod based on the torque information and the load information.

[0076] It should be noted that the torque information can be the thrust rod torque obtained by the strain gauge installed on the target thrust rod during the hand test. The length direction of the strain gauge is arranged at a 45-degree angle to the thrust rod shaft. Figure 4 , Figure 4 Figure 7 is a schematic diagram of the strain gauge installation positions on the target thrust rod. The angle between the first strain gauge 701 and the second strain gauge 702 is 90 degrees, and the angle between the third strain gauge 703 and the fourth strain gauge 704 is 90 degrees. These four strain gauges are connected in sequence to the Wheatstone full-bridge test circuit to test the torque of the target thrust rod, that is, the torque of the target thrust rod in the Y-axis direction.

[0077] Furthermore, in order to accurately obtain the torque information of the target thrust rod during the force test, the above step S31 may include:

[0078] Step S311: Acquire structural information of a target thrust rod in a target vehicle;

[0079] Step S312: generating an installation strategy according to the structural information, and installing a strain gauge on the target thrust rod based on the installation strategy;

[0080] Step S313: obtaining torque information of the strain gauge on the target thrust rod during the force test process.

[0081] It should be noted that, referring to Figure 5 , Figure 5 is a schematic diagram of the connection between the strain gauges. When the resistance value changes, the measured voltage e will change. Refer to the following formula 3, which is a formula for calculating the measured voltage change, where e is the measured voltage, E is the voltage applied by the test system, R1 is the resistance of the first strain gauge 701, R2 is the resistance of the second strain gauge 702, R3 is the resistance of the third strain gauge 703, and R4 is the resistance of the fourth strain gauge 704.

[0082]

[0083] When the target thrust rod is subjected to torsion, its principal strain direction forms a 45-degree angle with its length. Therefore, strain gauges arranged in this direction can measure strain under torsion. In this test bridge, the first strain gauge 701 is adjacent to the second strain gauge 702, and the third strain gauge 703 is adjacent to the fourth strain gauge 704. When subjected to ambient temperature fluctuations, the resistance of these strain gauges will change in the same manner. However, since these two gauges are located in adjacent bridges, these changes will cancel each other out. Consequently, the bridge remains balanced despite temperature fluctuations, without affecting the measurement, thereby improving test accuracy. Similarly, when subjected to axial tension, the resistance of the four strain gauges changes in the same manner, and the bridge voltage output remains unchanged, thus eliminating the influence of axial force.

[0084] Reference Figure 4 The sixth strain gauge 706 and the seventh strain gauge 707 form a pair to measure the torque of the target thrust rod in the Z-axis direction. When the target thrust rod is subjected to torque in the Z-axis direction, the surfaces of the sixth and seventh strain gauges 706 and 707 exhibit tension and compression, respectively. Therefore, the sixth and seventh strain gauges 706 and 707 are placed on adjacent bridges of the Wheatstone bridge, and strain output can be obtained by subtracting adjacent bridge outputs. However, when the rod shaft is subjected to axial force, the sixth and seventh strain gauges 706 and 707 exhibit equal strain increases or decreases. Based on the principle of subtracting adjacent bridge outputs, the strain is zero, thus eliminating the influence of the axial force. Furthermore, when affected by ambient temperature, the equal strain changes are also eliminated. The strains of the sixth and seventh strain gauges 706 and 707 are not affected by the torque of the target thrust rod in the X-axis direction, and are also largely unaffected by the torque of the target thrust rod in the Y-axis direction. Therefore, the torque of the target thrust rod in the Z-axis direction can be measured.

[0085] Similarly, the fifth strain gauge 705 and the eighth strain gauge 708 form a pair to measure the torque of the target thrust rod in the X-axis direction. The fifth, sixth, seventh, and eighth strain gauges 705, 706, 707, and 708 are arranged at a distance L / 2 of the target thrust rod's length. This ensures that, regardless of which end of the target thrust rod is fixed, the torque generated at the strain gauges by applying an equal load to the other end is the same, resulting in equivalent measurement results. This is particularly true given the symmetrical design of the target thrust rod, effectively avoiding measurement errors. The ninth, tenth, eleventh, and twelfth strain gauges 709, 710, 711, and 712, in sequence, form a Wheatstone full-bridge test circuit to measure axial force. Since the ninth strain gauge 709 and the eleventh strain gauge 711 are arranged on a pair of bridges, the bridges are additive, thereby eliminating the influence of torque. In addition, the ninth strain gauge 709 and the tenth strain gauge 710 are adjacent bridges, and the eleventh strain gauge 711 and the twelfth strain gauge 712 are adjacent bridges, which can play a role in temperature compensation, thereby ensuring that each strain gauge is not affected by changes in ambient temperature, thereby effectively improving test accuracy.

[0086] Furthermore, in order to obtain the unit load information of each strain gauge on the target thrust rod, the above step S313 may include:

[0087] Step S3131: performing relationship calibration on the strain gauge on the target thrust rod;

[0088] Step S3132: Obtain torque information of the strain gauge after relationship calibration during the force test.

[0089] It should be noted that after installing strain gauges on the target thrust rod, the force analysis equipment must also calibrate the force-strain relationship of each strain gauge. This means determining the load corresponding to each unit strain gauge. This allows the corresponding measured load to be calculated based on the strain test results. Before calibration, fix one end of the thrust rod and apply tensile forces or moments along the X, Y, and Z axes to the other end.

[0090] This embodiment obtains structural information of a target thrust rod in a target vehicle, generates an installation strategy based on the structural information, installs a strain gauge on the target thrust rod based on the installation strategy, obtains torque information of the strain gauge on the target thrust rod during a force test, and performs a force analysis on the target thrust rod based on the torque information and the load information. Since the present invention generates a strain gauge installation strategy based on the structural information of the target thrust rod and then installs the strain gauge on the target thrust rod based on the installation strategy, it ensures that each strain gauge is not affected by changes in ambient temperature, effectively improving test accuracy. The torque information of the strain gauge on the target thrust rod during the force test is obtained, and the force analysis of the target thrust rod is performed based on the torque information and the load information, thereby improving the accuracy of the thrust rod force analysis and effectively avoiding the problem of large force analysis errors caused by single data analysis.

[0091] In addition, an embodiment of the present invention further provides a storage medium storing a vehicle thrust rod force analysis program. When the vehicle thrust rod force analysis program is executed by a processor, the steps of the vehicle thrust rod force analysis method described above are implemented.

[0102] Furthermore, the force analysis module 30 is further configured to perform relationship calibration on the strain gauge on the target thrust rod; and obtain torque information of the strain gauge during the force test after relationship calibration.
