针对中型挖掘机液压系统不易标定的特点，应用AMESim软件建立了中型挖掘机执行机构及其相应液压系统的模型．分析了挖掘机在无执行机构动作时，液压泵的负流量控制特性；研究了无负载情况下，执行机构单独动作的压力流量特性，以及复合动作时各个执行机构的流量分配特性，为中型挖掘机液压系统的设计研究提供了参考．

This paper established the model of job device and their respective hydraulic system of medium-sized excavator based on AMESim. The negative flow control characterristics of the pump were analyzed when the job device was not moving; The flow and pressure characteristics of job devicers separate action joint action were studied in non-load conditions. Thus it provided a meth- od for the research of medium sized hydraulic excavator.
