三通管接头件是典型的用多向模锻工艺生产的工件，变形十分复杂。本文采用大变形弹塑性有限元理论，准确的接触边界处理技术和畸变网格的重划技术，使用ＡＮＳＹＳ５．０ａ软件经二次开发后，对三通挤压工艺过程及模具进行了二维有限元模拟，为工艺试验提供了可靠的理论依据
Tee fitting is a typical multi-direction forging production of the workpiece, the deformation is very complicated. In this paper, the large deformation elasto-plastic finite element theory, the accurate contact boundary treatment technology and the distortion grid re-dicing technology, the use of ANSYS5.0a software after the secondary development, the three-way extrusion process and the mold was two-dimensional finite Meta-simulation provides a reliable theoretical basis for the process test
