    摘要:

    【目的】为了回收车辆悬架振动过程中的机械能,基于所设计的振动能量采集型磁流变阻尼器和充电电路模块,进行振动机械能的回收研究。【方法】采用COMSOL软件对振动能量采集型磁流变阻尼器发电性能进行建模,并结合Simulink进行联合仿真,分析振动能量采集型磁流变阻尼器对1.2V锂电池的充电能力。设计和制作了全桥整流电路,同时搭建了实验测试系统。在振动频率4Hz、振动幅值8mm的正弦位移激励下,测试分析了感应线圈串联发电的能力。【结果】测试结果表明,感应线圈串联发电功率约为0.13W,由于机械振动的能量较为微弱且存在明显的电路损耗,使得实际充电功率低于仿真得到的0.22W;此外,在40秒时间内,该阻尼器对1.2V锂电池充电电量约为1.2mAh,完全充满需要1667秒。【结论】所设计的振动能量采集型磁流变阻尼器具有较好的充电性能。

    Abstract:

    【Objective】In order to recover the mechanical energy during the vibration of the vehicle suspension, a vibration mechanical energy recovery is conducted based on the designed vibration energy harvesting magnetorheological (MR) damper and charging circuit module. 【Method】The proposed vibration energy harvesting MR damper is modeled for power generation performance based on COMSOL software, and the charging capability for 1.2V lithium battery is also analyzed combined with Simulink for co-simulation. The full-bridge rectifier circuit is designed and fabricated, and the experimental test system is also built. The generating electricity abilities of the induction coils in series are tested under the sinusoidal displacement excitation with frequency of 4Hz and amplitude of 8mm. 【Result】The test results show that the induction coils in series can generate power of 0.13W, and it is lower than the simulated value of 0.22W. The reason is that the mechanical vibration energy is relatively weak and there exists circuit loss. In addition, the charging energy from the damper to the 1.2V lithium battery is about 1.2mAh within 40s, and it needs 1667s to fully charging. 【Conclusion】The relevent results show the developed MR damper has a good charging ability.
