摘要通过ANSYS软件建立不同直径和过渡圆角半径的阶梯轴三维模型,计算阶梯轴模型在纯扭转条件下的应力、应变;找出每个阶梯轴的最大应力及其存在的位置。根据计算结果,绘制最大应力随过渡圆角半径变化的曲线和随过渡圆角半径与小径比值的变化曲线,分析阶梯轴结构对应力集中程度的影响。 Based on the ANSYS software, the 3D model of the stepped shaft with different diameters and transition radius was established, and then the stress and strain of the stepped shaft model under pure torsion are calculated. According to the calculated results, both the curves of the maximum stress with the change of the fillet radius and the curve of the change of the fillet radius with the inferior arc are drawn, while the analysis of the influence of stepped shaft structure on stress concentration is given.
