| 摘 要： | 为了有效控制车辆悬架振动及回收振动能量，提出了一种基于滚珠丝杠式作动器和磁流变减振器的车辆馈能型混合悬架结构。建立了1/4车辆2自由度混合悬架动力学模型，分析了混合悬架的主动控制模式和具有电磁阻尼力反馈调节的半主动控制模式，设计了混合悬架多模式协调控制器，并利用MATLAB/Simulink软件对混合悬架多模式协调控制的动态性能、悬架系统的自供能进行了仿真分析，开展了混合悬架台架试验研究。仿真和试验结果表明：与被动悬架相比，随机路面谱输入条件下混合悬架的簧载质量加速度均方根减小了30%以上，混合悬架减振效果显著。

| Abstract: | In order to realize the damping control and regenerative energy recovery of vehicle suspension effectively， ball screw actuator and magnetorheological damper were introduced into vehicle suspension systems and a kind of regenerative energy hybrid suspension structure was put forward.For the following simulation analysis of suspension performance， a quarter vehicle dynamics model of hybrid suspension was established.The active control mode of hybrid suspension was analyzed， and the analysis of the semi-active control mode of hybrid suspension with feedback control of electromagnetic damping forces was done.The multi-mode coordination control system of hybrid suspension was designed.The dynamic performances and the self-powered of multi-mode coordination control of hybrid suspension were simulated by MATLAB/Simulink software.Then， the bench tests of hybrid suspension system were done.The simulation and experimental results show that compared with passive suspension， the root mean square of the body acceleration of hybrid suspension decreases by more than 30% under random roads.The damping effects of hybrid suspension system are obvious. |
