摘　　要：利用通过有限元方法计算的各种典型工况下的套简活齿内部应力，根据套筒活齿的几何和受力特点以及非线性回归方法，对多点受力套筒活齿的应力分析问题建立了应力计算的经验公式，从而解决了套筒活齿在几何尺寸不同、受力大小不同、力作用的位置不同以及受力个数不同时的应力分析问题。By use of the non-linear regression method and the stress data calculated by finite elementmethod, the stress formula for calculating the bending stresses in a movable sleeve tooth (mediumthick -wall cylinder) subjected to multi-concentrated radial loads, is developed. Compared with the fi-nite element method, under the condition of that the dimensions of the sleeve tooth as well as thenumber, the magnitudes and the actins positions of the loads on the sleeve tooth are arbitrarilychanged, this formula can be used to solve the problem of stress analysis of a cylinder more efficient-ly.
