Abstract：The geometric model and the finite element model of CDK66610CBEV vehicle chassis suspension system were established. And according to the requirements of the specific design conditions the definition and load boundary conditions were imposed. On the basis, the finite element analysis was completed, Finally got the stress and strain contours. According to the results of finite element analysis, the intensity and offset frequency were calculated. The results show that the strength and vibration frequency of the vehicle chassis suspension all meet the design requirements.
Key words：chassis suspension；offset frequency；harshness；the finite element analysis
