摘　　要：根据高速履带车辆行驶工况,确定了馈能减振器的基本结构,建立了馈能减振器制动力矩模型,并进行了影响因素分析.结果表明,馈能减振器输出的制动力矩受多因素影响,不仅是悬挂系统运动速度的函数,同时也是振动加速度、整流回路负载的函数.该馈能减振器从理论上能够通过控制回路负载来实现半主动振动控制.低传动比低转动惯量是馈能减振器应具备的基本特点,也是该电磁悬挂必须研究的一项关键技术.The structure of an energy regenerative shock absorber is described briefly according to the operating conditions of the suspension system for high speed tracked vehicles. A brake-moment model with multi-parameter is developed. It is demonstrated that the brake moment of the damper depends on its velocity,acceleration and the load of the electro circuit and therefore it is feasible to control suspension characteristics by adjusting the load of electro circuit. The load of the moment of inertia have a significant effect on brake moment while the suspension system is subjected to sever excitations,so a low-speed-ratio speed increaser and a low rotor moment of inertia motor are desired for the damper as well as with high torque characteristic.
