摘要:
汽车行驶时,路面的激励使得车身处于持续的振动状态.减振器将振动能量转换为内能耗散可提高车辆的平顺性,但面临着热失效的问题.设计了一套液压式能量回收系统,仿真结果表明该设计具有可行性.将振动能量转换为电能储存既可以延长电动汽车的续驶里程,又能彻底消除减振器的热失效,同时也有助于提高车辆的安全性和零部件的寿命,该成果的实用化也有利于主动悬架的推广和普及.

Research of Vibration Energy Recovery Based on Electric Vehicles
LIANG Xin-cheng, LI Yun-wu
Abstract:
Vehicles keep vibrating continuously due to road irregularity during driving. The shock absorber is a conventional component to keep vehicle riding comfort, and most vibration energy is consumed in the form of heat energy. Unfortunately, the shock absorber risks thermal failure because its temperature is so high. So it is essential to develop a vibration energy recovery system based on the hydraulic principle. Electric vehicles are environmentally friendly, but their driving ranges are limited by power battery technology. Hence, vibration energy recycling is significant for the electric vehicle industry. In this study, a vibration energy recovery system was designed, and simulation results verified the feasibility of the design. Simultaneously, the service life of the components of the vehicle were lengthened and its safety was greatly enhanced. In addition, active suspensions could be well promoted and high consumption rate of energy was reduced obviously.
Key words:  electric vehicle  road  shock absorber  hydraulic motor  vibration energy recovery
