ADAMS virtual prototyping software for the application platform,the study focuses on McPherson independent suspension systems and vehicle dynamics simulation,and then compared the riding comfort before and after the optimization of vehicle , in order to prove the vehicle ride comfort is improved,due to the change in the mass and the location of the center of a vehicle when refitting prue electric vehicle.The results show that the riding comfort is improved,and the method can shorten the development cycle of electric automobile,save development cost,it also has certain reference value when design electric vehicles equipped with traditional automobile suspension system.
