摘　　要：采用响应曲面法对φ34 mm同向旋转双螺杆挤出机的最大固体输送量进行研究。建立了以最大固体输送量为目标函数的二次式多项数学模型,探讨了目标函数的主要影响因素及其交互作用。结果表明,模型所预测的最大固体输送量和实验值之间的误差小于10%,当螺杆转速为124 r/min、螺纹元件螺旋升角为32°、物料粒径为2.7 mm时,最大固体输送量达到534 g/min,这比优化前的最大固体输送量提高了7.2%。The maximum output of solid convey for Ф34 mm co-rotating twin screw extruder was optimized by response surface methodology method. A quadratic multinomial equation model using the maximum output of solid convey as the objective function was built, and the main influencing factors and their corresponding relationships were discussed. It showed that the deviation between predicted values by the model and experimental values was less than 10 %. The maximum output of solid convey was obtained as follows, screw speed was 124 r/min, the helix angle of the screw was 32 °, and the diameter of the solid particle was 2. 7 mm. After optimizing the factors, the maximum output of solid convey was 534 g/min and was increased by 7.2 % compared with the value before optimizing.
