摘　　要：对液压挖掘机工作装置中的斗杆进行分析,选择斗杆受力最大的工况即斗杆和动臂垂直的位置,进行静力计算,得到斗杆主要铰接点的受力情况;根据计算结果,利用ANSYS Workbench进行斗杆有限元分析,得到斗杆变形云图,确定其变形最大和安全系数最低的部位;提出斗杆改进措施来提高斗杆的强度。It is an analysis of bucket linkage in a hydraulic excavator's attachment so as to find out the bucket link's most stressed conditions, i.e., a vertical position of bucket link and the boom to carry out a static computation to have got stress conditions at critical pivot points of the bucket linkage. And then, according to calculation results we utilized ANSYS Workbench to finite analyze the bucket link to have got a deformation cloud for defining a position of most deformation and lowest safety factor, before putting forth improvement measures for the bucket linkage to upgrade its strength.
