Description

Technical Field

[0001] This invention relates to a method and system for verifying the swing angle of the ball joint pin of an automotive stabilizer bar connecting rod, specifically a method for compensating the swing angle of the upper and lower ball joint pins based on the Rodrigues rotation formula. Background Technology

[0002] Stabilizer bars play a crucial role in vehicle roll control. Based on their working principle, the stabilizer bar's end needs to connect to the control arm or steering knuckle. When the stabilizer bar connecting rod is connected to the steering knuckle, the steering knuckle's vertical movement and rotation around the kingpin cause significant angular oscillation of the stabilizer bar connecting rod ball joint. However, the ball joint's oscillation angle is limited by the ball joint base, allowing only a certain angle. Therefore, suspension design requires verifying whether the stabilizer bar connecting rod ball joint's oscillation angle during suspension movement meets design requirements.

[0003] The following issues currently exist in verifying the swing angle of the stabilizer bar connecting rod ball joint pin:

[0004] 1. The mainstream method for verifying automotive suspension space is through the CATIA DMU module. Because the stabilizer bar connecting rod uses upper and lower ball joints, the CATIA DMU module typically uses a universal joint at one end and a ball joint at the other to simulate the movement of the stabilizer bar connecting rod. This results in the ball joint's swing angle being much larger than the universal joint's, making it impossible to accurately determine whether the stabilizer bar connecting rod's ball joint swing angle meets design requirements. Therefore, it is impossible to accurately verify the stabilizer bar connecting rod's ball joint swing angle.

[0005] 2. In the CATIA DMU module, the swing angle of the stabilizer bar connecting rod ball joint is checked. A rough method is to directly compensate the larger swing angle to the smaller swing angle and take the average value to compare with the design value to roughly determine whether the swing angle of the stabilizer bar connecting rod ball joint meets the design requirements. However, the actual rotation compensation of the stabilizer bar connecting rod is not a linear relationship, so this method cannot accurately check the swing angle of the stabilizer bar connecting rod ball joint.

[0006] 3. The Solid Contact command in the SD Motion module of Sim Designer can limit the swing angle of the ball joint pin of the stabilizer bar connector. When one end reaches the limit position, the transfer will automatically compensate the other end. This can solve the problem of inaccurate verification of the swing angle of the ball joint pin of the stabilizer bar connector by the CATIA DMU module. However, the modeling process requires defining parameters such as bushing stiffness, and the drive command control is very complex. This direction is rarely used. Summary of the Invention

[0007] To address the aforementioned deficiencies in existing technologies, the purpose of this invention is to provide a method, system, device, and storage medium for verifying the swing angle of the ball joint pin of an automotive stabilizer bar connecting rod. The verification method of this invention is based on the Rodrigues rotation formula, compensates for the swing angle of the upper and lower ball joint pins, and utilizes the programming function in EXCEL to create a macro, thereby achieving digital and intelligent verification of the swing angle of the ball joint pin of the automotive stabilizer bar connecting rod and improving development efficiency.

[0008] This invention is achieved through the following technical solution:

[0009] In a first aspect, the present invention provides a method for verifying the swing angle of the ball joint pin of an automotive stabilizer bar connecting rod, comprising the following steps:

[0010] S1. Based on the dynamic output suspension hard points, build a suspension DMU framework model in the CATIA DMU module;

[0011] S2. Drive the suspension DMU frame model with the law curve, activate the sensor, and output the coordinates of the six points required for the full travel of the suspension, including: the hard point of the ball joint pin on the stabilizer bar connecting rod, any point on the nut side of the theoretical axis of the ball joint pin on the stabilizer bar connecting rod, any point on the nut side of the installation axis of the ball joint pin on the stabilizer bar connecting rod, the hard point of the lower ball joint pin on the stabilizer bar connecting rod, any point on the nut side of the theoretical axis of the lower ball joint pin on the stabilizer bar connecting rod, and any point on the nut side of the installation axis of the lower ball joint pin on the stabilizer bar connecting rod.

[0012] S3. At any position in the full travel of the suspension, take the straight line containing the hard point of the upper ball joint pin and the hard point of the lower ball joint pin of the stabilizer bar connecting rod as the axis, and simultaneously rotate the nut side point on the theoretical axis of the upper ball joint pin and the nut side point on the theoretical axis of the lower ball joint pin of the stabilizer bar connecting rod at any angle θ, and record the coordinates after rotation in the full travel of the suspension.

[0013] S4. Based on the output coordinate points, calculate the upper and lower ball joint pin swing angles at any angle θ under the full travel of the suspension, and determine whether the swing angle of the stabilizer bar connecting rod ball joint pin meets the design requirements based on the calculation results.

[0014] Furthermore, in step S2, the vectors of six points at any position in the full travel of the suspension in the global coordinate system are obtained through the six coordinate points, and the upper and lower ball joint pin swing angles at any position in the full travel of the suspension are calculated using the vector formula.

[0015] Furthermore, in step S3, the coordinates of the nut side point on the theoretical axis of the ball joint pin on the stabilizer bar connecting rod and the nut side point on the theoretical axis of the ball joint pin on the lower stabilizer bar connecting rod are calculated using the Rodrigue rotation formula. The vectors of the two points after rotating by an angle θ at any position in the full travel of the suspension are obtained from the coordinate points.

[0016] Secondly, the present invention also provides a verification system for the swing angle of the ball joint pin of an automotive stabilizer bar connecting rod, used to implement the above method, including:

[0017] A module is built to construct a suspension DMU framework model in the CATIA DMU module based on the dynamic output of suspension hard points;

[0018] The output module is used to drive the suspension DMU frame model with the law curve, activate the sensors, and output the coordinates of the required points under the full travel of the suspension.

[0019] The execution module is used to rotate the nut side point on the theoretical axis of the upper ball joint pin and the lower ball joint pin of the stabilizer bar connecting rod at any position in the full travel of the suspension, with the straight line containing the hard point of the upper ball joint pin and the hard point of the lower ball joint pin of the stabilizer bar connecting rod as the axis, and record the coordinates after rotation in the full travel of the suspension.

[0020] The calculation and judgment module is used to calculate the upper and lower ball joint pin swing angles at any angle θ under the full stroke of the suspension based on the output coordinate points, and to judge whether the swing angle of the stabilizer bar connecting rod ball joint pin meets the design requirements based on the calculation results.

[0021] Thirdly, embodiments of the present invention also provide a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements a method for verifying the swing angle of the ball joint pin of an automotive stabilizer bar as described in any of the embodiments of the present invention.

[0022] Fourthly, embodiments of the present invention also provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements a method for verifying the swing angle of the ball joint pin of an automotive stabilizer bar connecting rod as described in any of the embodiments of the present invention.

[0023] Compared with the prior art, the advantages of the present invention are as follows:

[0024] 1. The swing angle of the stabilizer bar connector ball joint pin was checked using the CATIA DMU module. This solved the problem that the swing angle of the ball joint pin at the spherical end was much larger than that at the universal joint end when the CATIA DMU module used a universal joint at one end and a ball joint at the other end to simulate the movement of the stabilizer bar connector. This made it impossible to accurately determine whether the swing angle of the stabilizer bar connector ball joint pin met the design requirements.

[0025] 2. The swing angle of the stabilizer bar connecting rod ball joint pin is checked using the CATIA DMU module, avoiding the problem of inaccurately checking the swing angle of the stabilizer bar connecting rod ball joint pin caused by directly compensating the large swing angle part to the small swing angle part.

[0026] 3. The operation is simple. The simulation results of the CATIA DMU module can be directly imported into EXCEL to judge the swing angle verification result of the stabilizer bar connecting rod ball joint pin. This avoids the problem of having to define bushing stiffness and other parameters and control the drive command in the SD motion module of Sim Designer, which is very complicated, thus improving work efficiency.
