摘　　要：以某型液压挖掘机(20t级)为研究对象,基于SolidWorks、Hypermesh、Ansys三种软件无缝连接,利用各自软件功能特点对挖掘机反铲工作装置一动臂进行建模和分析,提出了一种快速、方便、高效的有限元分析方法,该分析方法能够快速建立三维实体和有限元分析模型并能保证网格质量和计算效率,同时也解决了不同工况共享有限元模型和销轴连接模拟的问题;分析结果表明该分析方法是切实可行的,对其他工程机械有限元分析的研究也具有一定参考意义。Ting a certain type of hydraulic excavator （20t）as the research object, based on the seamless connection of Solidworks, Hypermesh and Ansys and using the functions and characteristics of each software to model and analyze the arm of excavatar backhoe working device, it puts forward a finite element analysis method which is fas＇t, convenient and efficient. The an^dysis method can quickly build entity and finite element model and can guarantee the quality of grid and computational efficiency. At the same time, it also solve the sharing of the finite element model in different conditions and the simulation problem of pin shaft connection. The analysis results show that the analysis method is feasible and it has certain reference significance for the finite element analysis research of other engineering mechanical.
