取整个齿轮 ,对冲击载荷作用下的齿轮动应力进行有限元分析。研究了齿根应力随时间的变化情况及冲击载荷对临近轮齿的影响 ,并与静态结果进行了比较 ,并且分析了不同脉宽冲击载荷对齿根应力的影响。
Take the entire gear, finite element analysis of gear dynamic stress under impact load. The change of root stress with time and the influence of impact load on adjacent gear teeth were studied and compared with the static results. The influence of different pulse width impact loads on the tooth root stress was also analyzed.
