  要:该文采用扭转截面切应力分析方法,以实心和空心园截面为例,推导出与现有公式相同的最大切应力计算公式,用不同的方式证明了扭转时园截面切应力分布状况。文章给出了齿轴扭转最大切应力计算方法和公式,对类似情况的扭转切应力计算问题提供了方法。同时还对扭转切应力环流问题作了一定探讨。

AbstractThe same maximum shear stress calculation formula as the existing ones was derived by the analysis method of shear stress of reverse-section took the solid and hollow rounds as exampleswhich could provide method for the similar shear stress calculation formulas. And also discussing on the circumfluence of the reverse shear stress.
