摘　　要：回转系统能量损耗大、具有很大的回收潜力,为了提高挖掘机的节能性,本文提出了基于马达电机组和液压蓄能器两种回收方式复合回收的能量回收策略,并将蓄能器回收的能量储存在超级电容中进行再利用。采用AMESim仿真软件对回转制动能量回收过程进行了仿真分析。仿真结果表明,基于液压蓄能器与超级电容的复合回收方案可行,在制动时可以完成能量回收,可以有效提高系统的回收效率。The slewing hydraulic system has large energy loss and large potential of energy recovery. In order to improve the energy saving of excavator, the article proposes a energy recovery method for swing regenerative braking strategy, the system recover energy by both motor group and hydraulic accumulator at the same time, and store the energy recovered by accumulator in Super capacitor, the hydraulic simulation model of the system was based by AMESim, simulation result indicated that the system recover energy by both Super capacitor and hydraulic accumulator is feasible. The system can complete the energy recovery effectively, and improve the recovery efficiency of the system.
