The multi-body model of double- wishbone independent suspension was built by the use of vic- tual prototyping technology and the mechanical system dynamics analysis software ADAMS, the model was simulated to obtain the curve of toe angle,camber angle,caster angle and suspension stiffness orientation parameters with the wheels up and done the car' s movanent process, in the equilibrium position of the curve, the toe angle is in the zero point; Camber angle is slightly less than zero, it is about一0.03°;cash er angle is about 7.78°;kingpin indinat ion angle is about 9.4°.The simulation results compared with the prototype theoretical results show that the dynamic characteristics of the simulation models and the prototype vehicle suspension are basically the same, this method can accurately calculate the various performance of the suspension and improve the simulation precision and design efficiency.
