| 摘 要： | 采用多级有限元法对具有分析解的典型接触问题进行分析计算，将经过四次网格逐级细化后计算出的接触应力分布与分析解对比，证明可以采用多级有限元法精确分析接触区局部区域内的应力分布。经４次网格逐级细化后网格划分的细密程度较第一级可提高一万倍。

| Abstract: | The typical contact problems with analytical solution is analsed and calculated by bang multi-finite element method. The comparison between the analytical solution and the calculated contact stress distribution by using the fourth degree grill division proves that the multi-finite element method can be used to analyse the stress distribution of the local area in contaCt region precisely. In compariton with normal division,the detailed degree of the grill division through the fourthdegree division raises ten thousand times than that of the first-degree. |
