| 摘 要： | 本文针对非轴对称拔制金属管材三维速度场分析的问题，通过复变共形映射的理论，将非轴对称拔制问题映射成轴对称问题，继而以逆映射变换，将此轴对称问题返回到非轴对称管件拔制塑性变形速度场及空拔管壁厚均化的问题求解，提出了非轴对称管件三维速度场的二次映射变换法。

| Abstract: | About analytic problem of the 3D-non-axissymmetry metal pipe drawing velocity field, the papertransforms non-axis symmetry drawing problem into axissymmetry's with mathematics theory of the complex functionconformal transformation, solves non-symmetry metal pipedrawing velocity field and thickness homogeneity of the emptydrawing pipe with the reverse conformal mapping throughwhich the axis-symmetry problem is changed into non-axissymmetry's, and raises the quadratic mapping transformationmethod. |
