通过对车辆被动悬架减振器的阻尼功耗的估算,及其与一个最优主动悬架能量需求的比较,分析了主动悬架设计中回收振动能量的潜力。在振动能量回收可行性分析基础上,提出了一个馈能式电动主动悬架设计方案,并介绍了其结构和工作原理。初步的研究分析表明,所提出的新结构及控制方法可为车辆振动的主动控制和能量回收提供新途径,也为未来电动车悬架系统的电动化提供了必要的设计依据。

The energy consumption of a passive suspension via damper and the energy demand for an optimal vehicle active suspension are firstly investigated, showing valuable potential of vibration energy regeneration in an active suspension. Then, the feasibility of energy regenerative approaches is discussed, and an electrical active suspension configuration is proposed with the description of its working principle and structure. The feasibility study shows that the proposed configuration and control approach can be an effective approach for the active control and the energy regeneration of vehicle vibration. And potentially, it also can be useful to future electrical suspension design for electrical vehicles.
