【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.
