摘　　要：本文涉及一种新型的多流道熔体分配机头,其分配流道的设计能够尽可能保证熔体流动路径的一致性。运用基于有限元的CFD分析软件Polyflow对熔体进行了模拟计算,并运用后处理软件Fieldview,对三种不同流道的分配机头模型的压力场、速度场及黏度场进行了分析比较,得出了一些有关该新型分配机头的设计要点。This paper related to a new type of multi-channel distribution die,its design can be as much as possible to ensure the consistency of the melt flow path.By using CFD analysis software Polyflow based on finite element,the simulation was carried out on the melt,and used the post-processing software Fieldview to compare flow pressure,velocity and viscosity on three different distribution dies,and drew a conclusion of the design points for distribution die.
