弹性波发生器作用下柔轮变形机理的研究

摘要

This paper applies nonlinear FEM to calculate and analyse the flexspline distortion and the strain forces of the harmonic drive gear under flexible wave generator. Relevant principles and the conclusion of a linear relationship between the initial flexspline distortion and the strain forces are obtained. The calculation result matches with the test result.%利用非线性有限元方法对谐波齿轮传动柔轮在弹性波发生器作用下变形与变形力进行了计算分析，得到：柔轮径向变形量与径向变形力的相关规律，柔轮初始变形力与柔轮形变基本成线性关系。计算结果与实验结果对比显示，两者趋势吻合。
