| 摘 要： | 对安装有电流变阻尼器的半主动悬架进行数学建模,并在1/4车辆动力学模型上建立运动学方程和状态方程. 采用电流变阻尼器作为动作器,用开关控制对车辆模型进行模拟. 仿真结果表明:开关控制算法对悬架的动挠度、轮胎的动变形的控制是有效的,在一定程度上减低了车身垂直加速度,能有效提高车辆运行的平顺性和安全性. 开关算法所提供的是非连续控制信号,算法简单,效果好,有很好的应用前景.

| Abstract: | A mathematical model of semi-active suspension with electrorheological(ER) damper is built up,and its kinematic and state space equations are established on the basis of a 1/4 dynamic model.The ER damper has been simulated with two extensive on-off control methods.Simulation results demonstrated that the on-off control methods can effectively control the dynamic deflection of the suspension and that of the tire,and as a result diminish the body acceleration to some extent,improving the riding and handling characteristics.The on-off control can only supply non-continuous control signal but not the optimal continuum control signal.As a whole,the on-off control method has an outlook on application owing to its simplicity and effectiveness. |
