Abstract :
It can improve the stability of the vehicle by using non-linear spring, such as barrel-shaped helical spring, in vehicle suspension. The barrel-shaped helical spring on the rear suspension of PASSAT B5 was analyzed is this paper. Firstly, the accurate physical model of the spring is built by 3D scanning and post-process. Then the stiffness of the spring was calculated by finite element analysis, and the influences of the major structural parameters on the spring´s stiffness were obtained. Finally, the FE model of the barrel-shaped helical spring was validated with experiment results.
