| 摘 要： | 在每个接触点引入一系列测动坐标系，使三维接触问题转化为一系列可直接用线性互补的Ｌｅｍｋｅ算法求解的拟二维接触问题序列，逼近原三维接触问题的解，给出了加速收敛的算法。算例表明提出的方法是行之有效的。

| Abstract: | A sequence of slide coordinate systems is established at each contact point. The three dimensional problem with friction is transformed into the sequence of quasi-two dimensional contact problem with friction which are solved by linear-complementary Lemke arlgorithm.A method of accelerating convergence is presented.Examples show that the method is excellent. |
