通过经典Hertz理论计算点接触问题的局部应力,并采用有限元方法对点接触的局部应力问题进行深入的研究,利用ANSYS接触分析功能和APDL,对点接触问题进行有限元分析,通过网格的局部细化使得计算结果与赫兹理论解相近,为使用有限元分析软件求解此类问题提供依据。
The local stress of point contact problem is calculated by the classical Hertz theory, and the local stress of point contact is studied by using the finite element method. The ANSYS contact analysis function and APDL are used to analyze the point contact problem by the finite element method Local refinement makes the calculation results and Hertz theoretical solution similar to provide the basis for the use of finite element analysis software to solve such problems.
