Abstract

On the basis of the analysis and research on energy consumption required by vibration isolation of the related suspensions and the potential of energy recovery of the energy regenerative suspension, a new hydraulic energy regenerative suspension (HERS for short) is devised by using the dynamic pressure feedback method, which makes the dynamic damping raised. Then, the dynamic model of the new HERS is established and the simulations are compared between the new HERS and the passive suspension. The simulation results show that: the HERS has a better vibration-reduction effect than the passive suspension. Moreover, the former suspension can regenerate a certain amount of energy. The average power of a 1/4 suspension system with energy storage reaches 42.5 W. But some basic indices such as the dynamic travel of the suspension and the dynamic displacement of the tire will reduce to some extent.
