摘要
履带车辆半主动悬挂系统的建模,先作模型假设和简化,建立其系统二自由度振动模型。选定状态变量,得出悬挂系统状态方程和振动微分方程。利用线性最优控制的半主动控制算法算出控制力,并用 Simulink 对典型沙土路面激励下某型履带车辆半主动悬挂系统的响应仿真,结果表明该算法能很好控制车体位移和加速度。
For modeling of semi-active suspension system for track vehicle, the model was supposed and simplified, and vibration model with 2D of freedom of vehicle was established. The state equation and vibration differential equation of suspension system was set up through selecting state variable. The control force is calculated with semi-active control algorithm of linear optimal control. The effect of vibration control with the sand road excitation is simulated by Simulink software. The result shows that displacement and acceleration of the track vehicle are reduced greatly.
