Abstract: To solve the high energy consumption of standard active suspension system of vehicle, a 4 DOF energy-regenerative suspension system is established by taking the half-car as research object. A new energy-regenerative absorber, which has an actuator for active controlling and an energy-regenerator for energy harvesting, is designed to solve the problem of enabling to implement the active control and energy harvesting of energy-regenerative absorber at the same time. An energy management strategy based on the performing rate of active control is given according to the running conditions of vehicle. The simulated and experimental results show that, in comparison to the passive suspension, the comprehensive performance of the established energy-regenerative suspension with sliding mode control algorithm is improved by 22.700%, which indicates that the vibration control of the energy-regenerative suspension with sliding mode control is effective; 3 kinds of typical running condition, which are distinguished by road level and running speed, could be used as the criteria of the performing rate of active control.

Key words: ordnance science and technology, energy-regenerative suspension, energy-regenerative absorber, sliding mode control, energy harvesting performance, energy management strategy
