摘　　要：针对车辆传统主动悬挂系统高能耗的问题,以半车为研究对象,建立了一种4自由度馈能式悬挂系统;为解决馈能式减振器主动控制与能量回收不能并存的问题,设计了一种新型馈能式减振器,采用其力发生器进行主动控制,同时可用其馈能器回收能量。依据车辆典型行驶条件给出了基于控制执行率的车辆悬挂系统能量管理策略,以综合考虑馈能式悬挂系统的振动控制与能量回收。仿真分析与实车试验分析表明:与被动悬挂系统相比,所建立的基于滑模控制的馈能式悬挂系统的综合性能改善了22.7%,说明了该馈能式悬挂系统振动控制的有效性;依据行驶路面及行驶速度划分3种典型车辆行驶条件可以用来作为控制执行率实施大小的判别条件。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 en-ergy-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.
