本文简要地介绍了用有限元法计算渐开线齿轮轮齿弯曲应力的方法及计算结果,并与光弹实验的结果进行对比。文中还对齿轮的弯曲疲劳试验及齿轮的优化设计等问题作了说明。 In this paper, the method of calculating bending stress of involute gear tooth with finite element method is briefly introduced, and the results are compared with the results of photoelastic experiment. The article also describes the gear bending fatigue test and gear optimization design and other issues.
