摘　　要：　本文利用ANSYS和MATLAB软件,对衣架型和T型片材机头中熔体的温度分布进行三维有限元模拟和分析。通过对机头流道内温度分布的模拟,得出了衣架型机头流道的温度分布优于T型机头。The software ANSYS and MATLAB were employed to analyze and simulate the temperature distribution in the 'coathanger' and T-shaped sheeting dies based on the three-dimensional FEM. Through the simulation of temperature distribution in the dies, the melt temperature distribution in 'coathanger'die is better than that in T-die.
