摘　　要：液压挖掘机动臂是完成液压挖掘机各项功能的主要构件,其结构设计的合理性直接关系到液压挖掘机的工作性能和可靠性。基于有限元分析方法的液压挖掘机动臂结构分析是保证液压挖掘机动臂结构设计合理性的前提,以某型液压挖掘机(20t级)为研究对象,应用有限元分析软件ABAQUS对其动臂进行有限元分析,求得危险工况下该动臂的应力云图与位移云图,通过云图分析动臂的强度和刚度,为动臂的设计和试验提供参考。The arm is a main component of a hydraulic excavator for completing the function,the reasonability of the structure will directly affect the working performance and reliability of the hydraulic excavator. However,using the finite element method for structural analysis of excavator arm is the premise for ensuring the rationality for the structural design of the arm. Taking a certain type of hydraulic excavator（20t）as the research object,using finite element analysis software ABAQUS to carry out finite element analysis on its arm,from which the cloud atlas of stress and deform was obtained. The analysis results show that the strength and stiffness for the arm was sufficient and theoretical guidance for the design and test of the arm was provided.
