Abstract:

Based on the two⁃dimensional analytical modeling for the single⁃screw metering section of an extruder, a cross⁃validation method was employed to construct an artificial neural network (ANN) model and optimize its hyperparameters to effectively map the complex nonlinear relationship between the working conditions and structural parameters of the extruder and the productivity and power consumption. A multi⁃objective optimization of the structural parameters of the screw metering section was proposed using the ANN surrogate model combining with the NSGA⁃Ⅱ (non⁃dominated sorting genetic algorithm Ⅱ) algorithm, and the structural parameters of the optimal combination of productivity and power consumption were obtained through the TOPSIS (technique for order preference by similarity to an ideal solution) method. The relevant work is of theoretical guidance significance for the intelligent design of the structural parameters of the single screw metering section.

Key words: single screw structural parameters, artificial neural network, multi?objective optimization, Non?dominated Sorting Genetic Algorithm II
