摘　　要：本文以国内某公司生产的5.8t级小型液压挖掘机为样本。分析了此液压挖掘机回转液压系统原理,根据液压元件实际尺寸利用AMESim对本机采用的负载敏感液压回转系统进行建模仿真分析研究。通过仿真得出了液压马达压力起动和制动时具有较大冲击,压力波动比较大,负载敏感系统具有明显的节能效果,转动惯量对回转液压系统的主要影响。In this paper,A 5.8 ton hydraulic excavator is used as sample. Analysising the principle of slewing hydraulic system of excavator and base on accurate data the simulation model of slewing hydraulic system of hydraulic excavator is build by using AMESim software.Through the analysis of the simulation results, this paper gain that pressure of hydraulic motor have large impact, the load sensing system have obviously energy saving effection and moment of inertia, which affect the slewing hydraulic system.
