摘要: 研究了车辆半主动悬挂在速度反馈开关控制模式下的控制规律及系统幅频特性。通过仿真计算,对不同阻尼控制规律下系统的幅频特性进行了对比;分析了在单自由度半主动悬挂模型中的开关颤振现象及其原因;提出了以减振器的相对速度为反馈信号的能避免颤振的控制规律,简单且易于实现。

Abstract: The characteristics of on-off control based on velocity-feedback for semi-active suspentions of vehicle are researched. During the simulation, the characteristics of amplitude-frequncy for different damping control rules are compared, the tremble phenomenon due to the on-off control effect are analyzed. As conculusion, the new damping control rule is presented, which takes the relative velocity of damper as feedback signals of the on-off control, it able to prevent the system from the on-off tremble ,and simple to be relized.

Key words: On-off control On-off tremble, Semi-active suspention
