Abstract: In order to solve the problem of the electric vehicles tire was worn badly caused by the high levels of front wheel skid, Macpherson suspension virtual prototyping model was established in ADAMS/Car module. Based on sensitivity analysis; mainly quantities that affect front wheel positioning parameters was found. The relationship between front wheel positioning parameters and the arrangement of Macpherson front independent suspension was established. Macpherson suspension layout scheme optimization was carried out based on this. Based on the optimized suspension layout, virtual prototype model was established on the ADAMS/Car module. Steady rotation simulation test was carried out. The results show that the car with insufficient turning, and steady turning performance with no obviously variation before and after suspension optimization.
Key words: Macpherson front suspension; handing and stability; steady rotation simulation test; insufficient turning; ADAMS
