摘　　要：基于等效元素法建立了液压挖掘机工作装置的动力学模型,结合实例给出了运动微分方程的解,建模过程相比传统方法简单、高效。运用ADAMS软件对机构进行了动力学仿真,给出了仿真曲线。将YW1 6型液压挖掘机工作装置动力学解算结果与仿真结果相比较。The dynamics model of the working device of hydraulic excavator is established on the basis of Equivalent Finite Element Method. The solution of the motive differential equation of the system is given through an example. The process of establishing the dynamic model is simple and with of high efficiency than the traditional methods. ADAMS is used to do the dynamic simulation of the mechanism and the simulation curves is given. It is proved that this method of establishing dynamics model is accurate by comparing the solution of the motive differential equation with the simulation curve of YW16 hydraulic excavator.
