摘　　要：介绍了液电馈能式减振器的工作原理,结合液电馈能式减振器阻尼力数学模型和7自由度整车动力学模型,搭建了基于液电馈能式悬架的整车动力学仿真模型。以道路随机输入工况和道路正弦波输入工况为例,对装备液电馈能式悬架系统的整车动力学响应进行了分析,并与传统车辆进行了对比。仿真结果表明:基于液电馈能式悬架的车辆能达到传统车辆的行驶性能要求,且还具备能量回收的功能。This paper gives a describe of the working principle of hydraulic electromagnetic energy-regenerative shock absorber （HESA） and establishes a vehicle dynamics simulation model of HESA suspension based on the damping force mathematical model and 7 DOF vehicle dynamics model. Compared with traditional vehicle,the vehicle dynamic response of HESA suspension was analyzed in the same testing conditions of random road and sine wave road. The simulation results indicate that the vehicle of HESA can meet the working performance as the traditional vehicle,and have the function of energy regenerative in addition.
