摘要
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。
Pass classic Hertz theories computes locally stress of point contact,and adopt finite element method to thorough research problem of locally stress of point contact,make use of ANSYS of analysis function and APDL,rightness point contact problem carry on finite element analysis,pass part of mesh thin turn to make a calculation of result close by Hertz theories solve,provide a basis for solve this kind of problem of usage finite element analytical software.
