变刚度法在梯形齿同步带应力分析中的应用

从梯形齿同步带的材料非线性问题入手，以弹性平面问题的有限元法解平面应力问题为基础，引入梯形齿同步带的非线性有限元解法，即求解非线性问题的变刚度迭代法。用此方法对梯形齿同步带一个齿上的平面问题的应力分布进行了有限元分析研究。最后，通过一个具体算例求出梯形齿同步带一个齿上的最大应力点及应力分布规律并与弹性平面问题的解进行了比较。

Change Stiffness Method Used in Tooth Belt Stress Analysis

Beginning with the non linearity of synchronous belt material and based on the fixable plane problem of finite element method to solve plane stress problem,this paper inrtoduces the non linear finite element solution of synchronous belt.By this method, it researches the stress distribution of plane problem for a tooth on synchronous belt.Finally,through an example, the paper get a maximum stress point and stress distribution on a belt tooth and compare them with the solution of fixable plane problem.
