Abstract: In this study, the frequency domain analysis method is introduced for the analysis and design of nonlinear vehicle suspension systems. The explicit relationship between system output spectrum and model parameters is derived. By using optimization method, the optimal stiffness and damping of the nonlinear vehicle suspension system can therefore be achieved. Comparison studies indicate that the nonlinear vehicle suspension systems demonstrate obviously advantageous dynamics performance than the corresponding linear counterparts over all frequency bands. The optimal damping characteristic is not only a velocity-dependent function but also dependent on displacement.
