Research on the control and simulation of vehicle suspension systems

摘要：

A four degree-of -freedom half-body dynamic model of vehicle active suspension system is established.Road roughness height is modeled as a filtered white noise stochastic process.Based on control theory,the fuzzy control system of the active suspension is proposed.By using the matlab/simulink software,the simulation model is obtained.Simulation results indicate that the proposed active suspension system proves to be effective in the vibration isolation of the suspension system.What.s more,A mechanical model of four-degree-of -freedom half-body of vehicle passive suspension system is constitued,with the aid of software ADAMS.The combined simulation results demonstrate the effectiveness of the proposed mathematical model.
