The content of this research is as follows: Direct modeling for tooth surface of ti worm in ANSYS is difficult for the equations of contact lines being a kind of transcendental function.
主要研究内容如下：由于TI蜗杆齿面上的接触线方程是一种超越函数，直接在有限元分析软件ANSYS中建模比较困难。
Since the existence of embedded rotation surface with given principal curvature function is well proofed, the design and modeling of the surface becomes possible.
由于给定主曲率函数的嵌入旋转曲面存在性已得到较好证明，故使得曲面的设计成为可能。
UML technology-based augertype functional design method of"core to edge"and"trunk to refined"was adopted to make every function of the surface modeling system a comparatively well-defined arrangement.
使用UML技术，采用核心→边缘、主干→细化的螺旋式功能设计方式，使得所设计的曲面造型系统的各种功能拥有比较清晰的层次性。
