摘　　要：针对无极绳连续牵引车工作过程中大齿轮因疲劳失效而引起塑性变形的现象,对大齿轮进行受力分析,利用有限元软件ANSYS对其进行疲劳寿命分析和动力学仿真,研究其失效机理,并找出了大齿轮易发生疲劳失效的区域,减少了设计和试验成本,提高了生产效率,为大齿轮的设计制造提供依据。In the working process of endless-rope winch, plastic deformation of large gear possibly happen due to fatigue failure. For the phenomenon, this essay introduces force analysis of large gear. In order to explore its failure mechanism, the software ANSYS is used to analyze the corresponding fatigue life and dynamic characteristics, and the possible invalid area of large gear is able to be found, which reduces the trial cost and improves practical production efficiency, and then supports the gear design and manufacturing.
