摘　　要：以点接触为例 ,对ANSYS有限元分析计算结果与赫兹解进行比较 ,指出在利用ANSYS求解接触问题时 ,接触体的接触区及附近区域的单元网格边长应不大于接触椭圆的半轴长度 ,且小于接触椭圆短半轴长度的5 0 %时为佳 ,以满足有限元分析结果精度的需要。For the example of point contact,the comparing analysis on ANSYS finite element analysis result and Hertz′s solution has been made,when used ANSYS software to solve contact problem,element gridding edge length at the contact area and its adjacent area of contact bodies should be less than length of short half axis of the contact ellipse,as it less than 50% length of short half axis, so ANSYS software analysis result is accurate.
