The dynamic mathematical model of hydraulic shock absorber, which is suitable for the design and manufacture of the modern vehicle suspension system, is applied to effectively describe the relationship between the model parameters and the internal structure of the shock absorber, the setting of the components and the dynamic characteristics of the shock absorber. Dynamic mathematical model as a user model to join MSCAdams, to carry on the numerical simulation of vehicle system dynamics.With the speed-increasing passenger car bogie CW200 as an example, the dynamic mathematical model of hydraulic shock absorber is used to study the numerical optimization of vehicle suspension system parameters.Line test shows that the application The newly developed shock absorber can significantly improve the vehicle system dynamics.
