Nonlinear Analysis on Force, Rigidity and Damping Performances of Double Wishbone Independent Suspension with Coil Spring

Based on the principle of virtual work,the nonlinear function relations among the suspension stress,the coil spring rigidity and the suspension rigidity,the shock absorber damping and the suspension damping,are derived.Then a simple and useful double wishbone-coil spring independent suspension software for simulating analysis and designing is developed,and has been successfully applied to the designing of the suspensions of a mini electric vehicle.Using ADAMS establish double wishbone independent suspension model,through simulation the formula and conclusion are proved to be efficient and accurate.
