关于Hertz点接触理论适用范围的探讨

Discussion on Application Limit to Hertz's Contact Theory

通过对ANSYS有限元分析解和Hertz理论解比较,可以确定ANSYS软件对接触问题分析的计算结果是能够满足需要的。通过实例分析求解,指出Hertz点接触理论的适用范围是沟曲率半径系数f≥0.54(或者密合度≤0.925 99)。

Comparing ANSYS finite element analysis result with Hertz＇ s theory solution, it is confirmed that ANSYS software satisfies the requisites of contact problem＇ s accuracy. By solving of a series of examples, it is pointed out that Hertz＇ s theory solution is valid when groove curvature radius coefficient f≥0.54 （or osculation Ф≤0. 925 99 ） for ball bearings.
