摘　　要：利用流体动力学软件POLYFLOW对销钉螺杆挤出机的混炼段进行三维等温数值模拟。通过引入振动力场,采用粒子示踪分析方法对比分析不同振动力场参数对销钉螺杆挤出机混炼过程的影响。结果表明,振动力场对销钉的混炼性能有着明显的改善作用,但存在最佳的振动频率和振幅范围。该结论为寻求最优振动力场参数从而提高塑料混炼质量提供了参考。By using CFD software POLYFLOW, 3 - D isothermal numerical simulation is performed on the mixing section of a pin screw extruder. With the introduction of vibration force field and the adoption of particle tracking analysis, comparative study is carried out on the mixing behavior of this section under different vibration parameters. The results showed that vibration force field can remarkably improve the mixing efficiency of the pin mixing section, but this is only for some vibration frequency and amplitude range. The result gives references for researching and optimizing the polymer mixing quality with best vibration parameters.
