【Abstract】 In the paper, dynamic properties of vehicle suspension system are analyzed and discussed by numerical simulations. And, the 7 DOF theoretical model of an automobile is presented. The influence of the vehicle system parameters, such as stiffness and damping of the suspension as well as excitation of road surface, on the dynamic properties of running vehicle is discussed. Meanwhile, some dynamic characteristics of the model are researched within the time domain.更多还原
