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。Softwares ANSYS and MATLAB were employed to analyze and simulate the velocity, pressure and shear stress distribution in sheet extruder dies based on the three-dimensional FEM. Flowing character of plastics melt in the die was detected through the simulation of all of its distrbution profiles in different parts along the extruding direction.
