| 摘 要： | 提出了普通螺杆和屏障螺杆的计算机模拟方法，所用模拟包括：喂料区、固体输送区、熔融区和熔体输送区。在屏障型螺杆中，其固体熔融速率是按Ｔａｄｍｏｒ模型计算出来的，而Ｔａｄｍｏｒ模型的固体床速率是以固体床厚度和宽度的变化为基础的。模拟的数据同试验数据相比，可精确合理以预测出普通型和屏障型螺杆的挤出特性。

| Abstract: | A simulation method for both conventional and barrier screws extruder was presented. The overall models included submodels for the feed hopper, solids transport zone, melting and melt pumping. In barrier screw, the rate of melting of solids was calculated on the basis of Tadmor's model from solid-bed velocity and the change of solid-bed thickness and width. Comparison of simulation with experimental date showed that the behavior of both conventional and barrier screw extruders could be predicted precisely and reasonably. |
