基于Polyflow的一出二挤管机头模拟分析

Simulation for Pipe Molding Devices with Two Dies Based on Polyflow

介绍了Polyflow软件的特点及基本分析流程。以无规共聚聚丙烯(PP-R)圆管挤出为例,详细介绍了如何应用Polyflow进行挤管机头内流动场分析和口模逆向设计。结果表明,通过Polyflow能够预测熔体在机头内复杂的流动,并且利用其逆向挤出功能可以提高口模设计的一次成功率。

Features and basic analysis process have been introduced.Taking random copolymerization polypropylene(PP-R) pipe extrusion as an example,the process of flowing field analysis and inverse designing for a die was introduced.By using Polyflow software the complex flow of the melt could be predicted.
