A traditional suspension system is a passive suspension system. It consists of a linkage mechanism and a mechanical spring. And, geometrical structure is a crucial factor which determines the performance. The purpose of this work is to analyze an existing design namely ATV 500 manufactured by KYMCO Company. Firstly the background and relative parameters of this ATV is introduced briefly. Then a kinematic and simplified model analysis for the suspension steering system is derived along with the performance index. For improving the performance, the sensitivity analysis and optimization design are discussed based on the result of kinematic analysis. In addition, ADAMS software is used and verified that the derived kinematic analysis is feasible. The programming interface of kinematic analysis and simplified model for users is further provided. Finally, the optimization design based on the objective function of minimum change of kinematic parameters is performed. And, the result shows that the ride and handling performance are improved.
