Abstract:

A model was built for the energy regenerative suspension(ERS) using softwares MATLAB/SIMULINK and CARSIM. The noload voltage characteristic of the ERS was studied. The relationships between the damping factor and the charging capacitance as well as the compression speed were analyzed. The damping characteristic curves of the ERS were obtained. The results showed that the damping performance of ERS satisfies the need of the passenger car, at the same time it can recover some of the car vibration energy.

Key words: vehicle engineering, energy regenerative suspension(ERS), simulation, damping characteristic
