摘要
介绍了用于生产管材的螺旋机头及其主要设计方法和有限元建模方法,并用有限元软件POLYFLOW对机头内的熔体流动进行了三维模拟,分析了流道内的速度分布,压力分布和剪切速率分布,并指出了现有文献对螺旋机头的分析的某些不当之处。
The main design method for the pipe die with spiral mandrel and the creation of FEM modeling are introduced. Moreover, The 3D flow of polymer melt in the spiral die is simulated with POLYFLOW. The distributions of velocity, pressure and shear rate in the die are analyzed. Some inappropriate analyses of the spiral die in open literature are pointed out.
