%X 建立了销钉机筒挤出机的非牛顿流体流动模型，并计算出压力场、流动场和螺杆的特性曲线。结果表明，随着流体非牛顿特性的增强，螺杆的生产能力降低；随着螺杆螺槽上切口的增多，逆流增多，挤出产量降低；机筒上的销钉对挤出特性影响很小；销钉式挤出机的挤出特性与螺杆上有切口的挤出机的挤出特性相似。;A model for simulating the non-New tonian flow of rubber compound in pin barrel extruder was established.The characteristic curves of pressure field，flow field and screw were obtained by calculating with the model.The results showed that the extruder productivity decreased as the non-New tonian fluid characteristics of rubber compound strengthened and the backward fluxes resulted from the cuts on the screw channel increased；the pins on the barrel had little effect on the extrusion behavior；and the extrusion behavior of the pin barrel extruder was similar to that of the extruder with cut screw
