摘　　要： 用有限元软件对聚丙烯发泡体系挤出胀大现象进行模拟。讨论了不同配方对聚丙烯发泡体系挤出胀大的影响,并通过与实际实验对比,得到模拟膨胀率的修正值,通过考虑修正值发现,总模拟膨胀率与实验膨胀率的值及其变化趋势基本吻合,为发泡体系的流场模拟分析提供了理论依据。 The die swell in PP foaming system was simulated with finite element software. The effects on die swell ratio of different formula in PP foaming system was discussed. The corrected value of simulated swell ratio was gained by analyzing the relationship between the simulation and the experiment. Considering the value, it was found that the total simulated swell ratio was approximately the same as the experimental result. The theoretical foundation of foaming system simulation was provided.
