| 摘 要： | 采用显示动力分析软件ANSYS／LS—DYNA建立复合胀形三维有限元模型，深入研究了三通管液压胀形过程中应力应变分布规律，系统比较了轴向压缩胀形和复合胀形过程中应力应变变化规律、胀形支管高度、壁厚分布的差异。研究表明：复合胀形较轴向压缩胀形应力应变分布更均匀、壁厚分布更均匀、更易获得较大的支管高度。

| Abstract: | Three-dimensional model of T-branch tube compound bulging has been established by using advanced explicit finite element codes ANSYS/LS-DYNA with the research of distribution law of equivalent stress and plastic strain.Subsequently,wall thickness distribution and variation of the branch height in compound bulging and axial-compressive bulging have been systematically compared which indicates that much more uniform stress and strain distribution, wall thickness distribution and bigger branch height could be got from compound bulging. |
