Modeling and Simulation of K Characteristics of a MPV Front Suspension

The control stability of a MPV model developed by a company is estimated and evaluated in advance. In ADAMS/Car, the McPherson suspension assembly and the steering system model are established for this model of car, and the two-wheel synchronous excitation is applied to the wheel. The model is adjusted by the KC test data of the suspension of the race car to achieve a certain precision. After adjusting the model parameters, the model is simulated with two-wheel parallel pulsation and side tilt. The simulation results show that the changing trend of the four-wheel positioning parameters is reasonable, and the initial value setting meets the design criteria. The model can guide the matching of the front and rear suspension of the new vehicle and the realization of simulation of the whole vehicle stability.
