摘要:
悬架系统是汽车的关键部件，对汽车的平顺性有重要的影响。通过建立单自由度1/4汽车模型得到动力学方程。采用龙格–库塔法对系统方程进行数值分析，并通过改变激励参数得到系统的临界振幅及揭示混沌现象。通过MATLAB/SIMULINK软件对系统进行控制仿真，滑模控制可以用来解决强非线性振动的控制问题，可以实现对悬架系统的实时控制，且具有良好的鲁棒性。The suspension system is a key component of the car, and it has a significant impact on the car ride. 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.
