Based on the theory of mutibody dynamics, a virtual prototype model of a vehicle is built by ADAMS. The impact of suspension system on comfort for the crew and the laws of damage of vehicles on the road are studied. Numerical calculation carried out in terms of the Appraisal criterion of the ride comfort and road friendliness, the influence of traveling speed, suspension spring stiffness and shock absorber damping upon vehicle ride comfort and road friendliness was analyzed, and optimized suspension parameters is obtained in the end. Through the analysis of comparison with dynamic tire force before and after optimization, some helpful conclusions about suspension design and application were achieved.
