In view of the problems in the use of wheel side drive system, torsion beam type electric driving axle is proposed for the solution. First, with the vehicle parameters of a certain electric vehicle as a sample, the torsion beam driving axle is matched and designed and the three-dimensional model was drawn with the help of CATIA; secondly, the stiffness and strength of the driving axle are analyzed with the help of ANSYS software under five working conditions; finally, the modal analysis of the driving axle structure is carried out. It is verified from the three aspects of stress, deformation and inherent mode that the designed driving axle can meet the limit requirements of China's national standards for vehicle driving axles, which proves the rationality and effectiveness of the design scheme.

“…Hyun et al studied a torsion beam multibody dynamics model based on coupling the hard points and characteristics of the torsion beam and used this model to predict the change of dynamic response. Finally, through the test, the results show that even if the shape of the torsion beam is uncertain, the torsion beam model based on the beam element can easily predict the system according to the changes in the hard points and the performance of the torsion beam [6]. Zhan et al used three-dimensional digital image correlation (DIC) technology to test the deformation of the weld zone of torsion beam suspension system.…”

The structure of torsion beam suspension is analyzed, and based on the real vehicle, the torsion beam suspension coupled with flexible torsion beam and the multibody dynamics model of vehicle is established. The influence mechanism of torsion beam opening angle and rubber bushing installation angle on roll center and roll stiffness of suspension is systematically analyzed. Under different opening angles of torsion beam and different rubber bushing installation angles, a comparative analysis of the changes of the toe angle and camber angle is carried out when the torsion beam suspension is moved and subjected to force. Based on simulation of the sine swept steering input of vehicle, the frequency response characteristic index of vehicle is taken as the optimization objectives, the opening angle of the torsion beam and rubber bushing installation angle of the vehicle are taken as the optimization variables, and performance of the whole vehicle is optimized by using multiobjective optimization algorithm. The optimized vehicle and original vehicle are compared with the frequency response characteristics and steady-state characteristics. The results show the frequency response and steady-state characteristics of the optimized vehicle have been improved.
