摘　　要：松土器是推土机的主要工作装置之一,针对松土器工作中3种典型工况在SolidWorks Simulation中进行有限元分析;通过对计算结果的分析,找出松土器受力时超过许用应力的区域,提出了改进意见。对修改后的模型重新进行有限元分析,分析结果显示改进后的结构在受力时其关键部位没有出现超过许用应力的现象。The ripper is one of the main working device of a bulldozer. In this paper, the finite element analysis of the ripper is conducted by SolidWorks Simulation under three typical working conditions, and the regions whose stress are over the allowable value are found out through the calculation result analysis. Suggestions for improvement are proposed. The finite element analysis on the improved structure shows that there is no region whose stress is over the allowable stress.
