移动载荷下齿根应力的时间历程

Time History of Spur Gear Root Stress under Moving Load

利用有限元方法研究了直齿圆柱齿轮在移动载荷作用下的齿轮齿根弯曲应力随时间的变化情况。并对二维有限元和三维有限元结果分析进行了比较。

In this Paper, the variation of the dynamic root stress with time under moving load is investigated by means of FEM (Finite Element Method). The results by means of 3-D FEM are compared to those of by means of 2-D FEM.
