Abstract

McPherson Suspension is researched with multi-body dynamics and Suspension Kinematics theory. When the front rubber bushing stiffness of lower control arm is changed, the suspension performance is analyzed and discussed in the vertical bounce, roll bounce, brake force and drive force. The conclusion is drawn that stiffness of front rubber bushing in all directions has no effect on the suspension performance in the vertical bounce and roll bounce. In the brake force and drive force radical stiffness of rubber bushing has heavy effect on the suspension performance and axial and torsion stiffness of rubber bushing has a little effect on the suspension performance.
