Through the establishment of a single degree of freedom quarter car model we obtain dy- namic equation. We use Runge-Kutta method for numerical analysis of the system equations and obtain parameters by changing the amplitude of the system and reveal the critical amplitude chaos. By MATLAB/SIMULINK software analysis, sliding mode control can be used to solve the problem of strong nonlinear vibration and achieve real-time control of suspension system, and it has good robustness.
