The kinematics characteristic is directly related to handing and stability, and use performance of the automobile. And the study of suspension kinematics is one of the most important subjects of research of vehicle design.The paper describes the current research status of the kinematics of automotive suspension system, through the specific classification and analysis of the automotive independent suspension system, Macpherson suspension system was chosen to be analyzed, I下载后可任意编辑through the analysis of the structure, arrangement and dynamic characteristics of the Macpherson suspension, a virtual prototype model was accomplished by the assembly design of the 3D models of this suspension system, by using the software ADAM. In the end, the Macpherson suspension is analyzed by multi-body system dynamics software ASAMS. The Macpherson suspension mechanism was driven by the up and down movement of the wheel,the determination of the positional parameter characteristic of the McPherson suspension, and making a simple analysis.Keywords: McPherson suspension; kinematics simulation; CATIA; wheel alignme...
