摘　　要：挖掘机液压系统的能耗损失中,管路系统的压力损失所造成的功率损失不容忽视。针对某公司生产的21t液压挖掘机,选取铲斗联液压系统为研究对象,利用理论推导、AMESim软件仿真以及试验研究对铲斗联液压系统的管路压力损失进行了分析计算,得出相应的压力损失值分别为0.793、0.82、0.83 MPa。从而说明在铲斗联液压系统压力损失的研究中,理论研究的可行性、软件建模计算的有效性以及试验研究的必要性。During the energy losses of Excavator hydraulic system, the power loss caused by pressure loss in the piping system can not be ignored. Aimed at the 21t hydraulic excavators manufactured by one company, the bucket united hydraulic system was chosen as the study object. The pressure loss in the pipeline was calculated and analyzed through the theoretical derivation, AMESim software simulation and experimental study. The obtained corresponding pressure loss values were 0. 793, 0. 82 and 0. 83 MPa. Thereby it shows the feasibility of the theoretical study, the validity of the software modeling calculation and the necessity of test study in the study of united hydraulic system pressure loss.
