摘　　要：螺杆构型对胶料的挤出塑化质量有着至关重要的影响。文中使用ANSYS Polyflow仿真软件,对不同构型的5种场协同扭转螺杆进行了非等温瞬态流动模拟研究,分析了不同构型螺杆的混合性能,传热性能及塑化均匀性等,并与普通双头螺纹螺杆进行了对比。结果表明,相比于普通螺纹螺杆,5种场协同扭转螺杆的综合性能均有所提升,其中螺杆F的混合性能最佳,螺杆B的传热性能最佳。场协同扭转元件诱导产生的螺旋流动可以增加流场中的拉伸流动和拉伸形变,改善胶料速度场、速度梯度场与温度梯度场之间的协同性,增强传热传质,提高胶料挤出质量,符合场协同原理。The screw configuration is an important factor directly affecting the plasticizing quality of rubber extrusion.Through ANSYS Polyflow software,the non-isothermal transient flow simulations were conducted on five different field synergy torsion screw configurations with varying arrangements of twisted elements.A comparison was made with a conventional double-threaded screw,and the analysis focused on the impact of different screw configurations on extrusion performance factors such as rubber material mixing,heat transfer,and plasticization uniformity.The results indicate that all five field synergy torsion screw configurations outperform the conventional threaded screw in terms of overall performance.Among them,screw F exhibits the best mixing performance,while screw B shows the best heat transfer performance.The helical flow caused by the twisted elements in the field synergy torsion screw can enhance the synergistic interaction between the velocity field,velocity gradient field,and temperature gradient field of rubber material,which increases stretching flow and deformation in the flow field,enhances radial heat and mass transfer,thereby improving the plasticizing quality of rubber material.This process aligns with the principle of field synergy.
