摘　　要：利用ANSYS有限元软件对具有反向螺纹的啮合异向双螺杆元件的流场运动规律进行数值模拟,研究豆粕在其流道中的运动情况,分析了宏观速度场、压力场的基本规律以及反向螺纹区的特性,并和普通螺杆进行对比分析。结果表明:组合螺杆增加了豆粕在挤出机的停留时间,改善了混合分布能力。研究结果可为双螺杆挤出机加工提供理论参考。The three-dimensional flow field of counter screw was analyzed base on the software of ANSYS. analysis soybean meal in the flow channel with a twin-screw area of sports, including velocity field and pressure field, the flow characteristics of conventional screws are compared with those of combined screws. The results indicate that combined screws extended the time of the soybean meal in the barrel, in favor of mixed materials. The research could provide references for twin screw extruder processing.
