摘　　要：利用ANSYS和MATLAB软件,对缩放型片材机头中熔体的速度、压力和剪切应力的分布进行三维有限元模拟和分析。通过对机头流道不同截面处熔体场量分布的模拟,探知了熔体在流道内的运动规律及特点。The software ANSYS and MATLAB were employed t o analyze and simulate the velocity, pressure and shear stress distribution in the extrusion sheet die based on the three-dimensional FEM. The flowing properties of plastics melt in the die was detected through the simulation of all of its d istribution profiles in different parts along the extruding direction.
