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：继而以逆映射交换，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受换法
In this paper, aiming at the problem of three-dimensional velocity field analysis of non-axisymmetric drawn metal pipe, the problem of non-axisymmetric drawing is mapped into axisymmetric problem by the theory of complex conformal mapping. Then the problem of axisymmetry is returned To non-axisymmetric pipe drawing plastic deformation velocity field and the empty pipe wall thickness homogenization problem solving, proposed non-axisymmetric pipe three-dimensional velocity field by the second mapping method
