摘　　要：针对层叠式取向机头和普通挤出机头两种不同构型的机头安装在挤出机上,在相同的机头压力、机头温度和螺杆转速等实验条件下进行挤出成型对比实验,并采用有限元模拟的方法对层叠式取向机头和普通挤出机头流道内的压力场进行了对比分析,保证短纤维增强橡胶复合材料的挤出成型及其质量。结果表明,层叠式取向机头使短纤维在橡胶基体中的径向取向度比普通挤出机头高,对短纤维增强橡胶复合材料的挤出成型质量及性能也比普通机头要好。Under the same experimental conditions such as head pressure, temperature and screw speed, A contrast experiment research was made between the cascading extrusion head and normal excavation head which installed in the extruder. And the contrast analyzed the pressure field adopts the method of finite element simulation to ensure that the short fiber reinforced rubber composite extrusion forming and its high quality. The results show that cascading orientation head can make radial orientation degree of short fiber in rubber matrix higher than normal extrusion, and reinforced rubber composite extrusion forming quality and the performance is better than normal head too.
