摘要

Suspension system is the key component of vehicle for riding comfort and stability. This paper describes how to design and analyse the suspension system. According to the tire characteristics, geometric parameters of the transverse arms, elastic elements and damping elements are firstly determined. Then the dynamic model of the vehicle suspension system is established. Finally, the kinematic and dynamic analysis are carried out to verify the effectiveness of the suspension system design. According to the analysis results, the benefits of the design method is evident.
