Abstract
Continuous vibration energy of vehicle body is converted into heat and dissipated in the air when it is driven. The service life of shock absorber will be reduced at high temperature. An energy regeneration system is designed in this paper to convert vibration energy of vehicle body into electrical energy, which prolongs the driving range of electric vehicle. The dynamic model of shock absorber is built to simulate the characteristics of force-displacement and force-velocity. The simulation result is compared with the test one. The energy regeneration system model is established and compared with the general shock absorber. Further, we simulate the quarter-full vehicle model which is established with general shock absorber and energy regeneration shock absorber respectively in DSHplus, compare the simulation results, and use a bench experiment to testify the simulation result. The test results show that the energy regeneration model not only retains shock absorber function but also convert vibration energy into electrical energy.
