英文摘要：

A new energy-regenerative type electric suspension is proposed, and experimental studies are performed on its prototype in this paper. Firstly, the working principle and structure of the energy-regeneratlve type electric suspension are described. Then, the motor actuator prototype is designed based on the parameters of rear suspension of a specific passenger car, and the performance test of the electric motor is carried out. Finally, the bench test on complete car is conducted to examine the energy regenerative characteristic and suspension performance of the designed electric suspension system at follow-up state. The results show that in low frequency and large amplitude conditions, the electric suspension at follow-up state can transform some mechanical energy into electrical form while basically maintain car performance.
