摘　　要：液压挖掘机回转系统启动过程中存在严重溢流损失,提高启动速度和减小溢流损失很难同时实现,尤其是对于中大型液压挖掘机.利用AMESim和ADAMS仿真软件,建立挖掘机回转系统的机——液联合仿真模型,分析相关参数对回转启动性能的影响,通过优化系统参数,减小启动溢流损失的同时提高了启动速度.Overflow losses seriously exist in the start-up process of hydraulic excavator＇s slewing system, while improving the start-up speed and reducing overflow losses is difficult to be simultaneously achieved, especially for medium and large hydraulic excavators. This article established the AMESim-ADAMS co-simulation model of excavator＇s slewing system, analyzed the influence of the rotary system＇s main parameters, optimized the main parameters, and reduced overflow losses as improving the startup speeds.
