Abstract

Multi-link independent suspension is built according to the hard point parameters of a car. Using multi-body dynamics and suspension kinematics theory, the suspension performance were analyzed under the simulation test of parallel wheel travel, loading brake force after the outer rubber bushing stiffness of the under control arm is changed. The conclusion is drawn that axial stiffness of rubber bushing has almost no effect on the suspension performance, but radical stiffness has a little effect and torsion stiffness has the biggest effect on the suspension performance of these three parameters.
