Performance Analysis of Rear Rubber Bushing Stiffness of Lower Control Arm on Front Double Wishbone Independent Suspension

摘要

Front double wishbone independent suspension is built according to hard point parameters of a car. After the rubber bushing stiffness of under arm is changed, the suspension performance is analyzed and discussed with multi-body dynamics and Suspension Kinematics theory. The conclusion is drawn that axial and torsion stiffness of rubber bushing has a little effect on the suspension performance, but radical stiffness of rubber bushing has heavy on the suspension performance.
