摘　　要：针对现在普遍采用的液力式主动悬架系统的响应慢、能耗大、结构复杂等缺陷,采用滚珠丝杠结合永磁直流无刷电机结构的馈能式电动悬架,其最大特点是能够在保证悬架减振特性的基础上,将不平路面激励引起的悬架系统振动能转化为电能并回收利用.依据某车型的后悬架系统参数,设计和试制了电动悬架系统样机,在系统特性试验及性能分析的基础上,通过整车台架试验检验所设计的电动悬架系统在随动状态下的馈能特性和悬架特性.通过对试验数据的分析,验证了回馈振动能量的可行性.Current hydraulic active suspension system has several defects such as slow response, high energy consumption and complex structure. An energy-regenerative electrical suspension was adopted whose motor actuator is composed of a permanent-magnet direct-current motor, a ball screw and a nut. The significant characteristic of the suspension is that it can regenerate the vibration energy from the road excitation and transform it into electric energy and meanwhile maintain good isolation performance. The prototype was designed and produced based on the rear suspension structure of a typical passenger car. The performance tests of the DC motor were carried out. The regeneration and vibration control performances were verified by the full-vehicle experiments in the IST roadlab four post rig. The experimental results of the electrical system working as a passive suspension system show the feasibility of vibration energy regeneration.
