摘　　要：以某型号液压挖掘机的工作装置为研究对象,在AMESim环境下,根据实际液压元件的特性和工作装置的尺寸参数,对挖掘机工作装置的液压系统和机械系统进行了建模,实现了其液压系统动态仿真和机械系统的动力学仿真,这种建模方法提高了系统仿真的效率。对典型工况下,工作装置机械系统的运动特性和液压系统的工作特性仿真结果进行了分析,仿真结果与实际相符,该模型可实现机液耦合系统的综合仿真,这种建模研究方法为挖掘机机械系统结构设计和液压系统的优化设计提供了一种有效的手段。Taking a certain type of hydraulic excavator＇s manipulator as the research object,the hydraulic system and mechanism of excavator＇s manipulator were modeled in AMESim using the actual characteristics of hydraulic elements and measurements of manipulators. Then the dynamic simulation of hydraulic system and the planar dynamic simulation of mechanism were achieved,such a modeling approach improved the efficiency of system emulation. It analyzed the simulation results of the hydraulic system and mechanism of excavator＇s manipulator,the simulation results matched with the practical ones. The model can realize mechanical-hydraulic simulation and the modelling method can provide an effective way for the design of mechanical system structure and the optimal design of hydraulic system.
