矩形管挤压过程数值模拟

In this paper, the porthole die extrusion process of 6063 aluminum rectangle tube is simulated by both finite element method (FEM) and finite volume method (FVM).Compared the different simulation results obtained by FVM and FEM, it can be conclude that FVM is a more usable method to simulate the extrusion process of rectangle tubes than FEM. The simulated results such as the distribution of velocity, stress, strain and temperature are given respectively through simulating the extrusion process which are helpful for the structure design of porthole die and the optimization of die parameters.
