In order to reasonably match suspension stiffness and realize the optimization of vehicle ride comfort, a time-domain virtual prototyping model of the 8×4 heavy vehicle is established based on dynamic software ADAMS, and its vertical vibration responses are simulated and analyzed on road level B. After that, an optimal design method for heavy vehicle’s suspension system is put forward. In this proposed method, the first, the second axle suspension stiffness and the balance suspension stiffness are taken as the optimal variables and the maximum values of Z-direction power spectral density (PSD) of the cab and cargo boxes mass center are chosen as the optimal target. By using SQP (Sequential Quadratic Programming) algorithms to conduct optimizing calculation, thus the optimal suspension stiffness parameters are obtained, which promotes and improves the heavy vehicle’s ride comfort.
