| Abstract: | The model for variable diameter copper tube has been established by use of finite element analysis software MSC.MARC. The simulation of tube hydraulic bulge process has been finished. The analysis of wall thickness and equivalent strain has been conducted to the finished tube. The reasonable matching relationship between axial feeding and inner high pressure of tube has been obtained. It is obtained that wall thickness the largest region of thickness reducing rate and stain is at the connection of both ends chamfer and largest bulge domain. |
