| 摘 要： | 针对传统汽车悬架不能将振动能量回收利用的缺点,提出了一种基于无级变速器速比控制实现悬架阻尼调节且可实现车身振动能量回收的电磁半主动悬架设计方案。在分析其结构和工作原理的基础上,基于动力学分析建立了无级变速器速比与悬架阻尼之间的对应关系以及该悬架系统的动力学方程；设计了无级变速器速比PID控制器,以1/4汽车悬架系统为例,对汽车平顺性以及振动能量回收效果进行了仿真分析；仿真结果表明,通过对无级变速器速比进行控制调节悬架系统阻尼,可以实现良好的汽车平顺性,并可实现车身振动能量的回收。

| Abstract: | In this paper, an electromagnetic semi-active suspension system is proposed, whose damping is adjusted by Continuously Variable Transmission(CVT)speed ratio control and the body vibration energy can be recycled. The structure and work principle of the suspension system is analyzed, and the relationship between the speed ratio of CVT and the suspension damping as well as the dynamics equations were established based on the dynamic analysis; PID controller for CVT speed ratio is designed, and taking 1/4 vehicle suspension system as an example, the vehicle ride comfort performance and vibration energy recovery effect are simulated and analyzed; Simulation results show that good ride comfort can be achieved by controlling CVT speed ratio to adjust damping of the semi-active suspension system and the vibration energy can be recycled which leads to the improvement of the vehicle economy . |
