给出了三维摩擦接触问题的一个非光滑混合不动点模型及算法，这种算法无须求导数，没有引进任何额外变量，并且可视为一种三维摩擦接触问题的迭代法，利用非光滑分析和不动点理论对算法做了分析，给出了算法的不动点理论背景及算法的理论分析，为模型解的存在性及算法收敛性提供分析依据，最后给出了相应的数值算例。

The features to evaluate the tooth contact quality such as the location of the contact point on the tooth surface, clearance between the meshing tooth surfaces, curve of the transmission error and the path of the contact point are investigated. The accurate geometric representation with non-uniform rational B spline of the worm and the wheel tooth surface is presented then the corresponding program is developed.
