Numerical simulation in the porthole dies extrusion of aluminum harmonica-shaped tube;

分流组合模挤压铝合金口琴管的数值模拟

The deformation behavior of metals in harmonica-shaped tube extrusion process was analyzed.

分析了铝合金口琴管挤压过程中的金属的流动和变形行为,获得了速度场、温度场、应力场和应变场的分布图,数值模拟结果与理论分析结果吻合较好。

In this study,according to the rigid-viscoplasticity finite element method,the porthole die extrusion process of an aluminum harmonica-shaped tube in the welding chambers with different heights was simulated using Deform-3D commercial software.

基于刚粘塑性有限元理论,采用DEFORM-3D有限元商业软件,对3种不同焊合室高度下的薄壁多孔口琴管挤压过程进行数值模拟。
