Abstract

In this study, an artificial neural network (ANN)–based method is presented to predict the experimental effective demolding forces (EDFs) produced during the injection molding of a polycarbonate polymer material. To evaluate the prediction accuracy and capability of the proposed method, three different algorithms, namely Levenberg–Marquardt (lm), BGFS quasi-Newton (bfg), and scale conjugate gradient (scg), were included in the proposed model. The generated models were validated by comparing the experimental and ANN results, which showed good quantitative agreement. The performance of the algorithms was evaluated using the R2 and root mean square error (RMSE) values, which indicated that scg exhibited the best performance with an R2 of 0.9655 and an RMSE of 0.0223. The relative contribution plot of the ANN models showed that packing pressure had a stronger influence than mold temperature, filling time, and melt temperature. These results will form the basis for predicting the EDF of a comparable molded part using ANN and will help to significantly improve the demolding properties of polymer materials.

基于人工神经网络的注射成型过程脱模力预测模型
本文提出了一种基于人工神经网络(ANN)的方法来预测聚碳酸酯聚合物材料注射成型过程中产生的实验有效脱模力(edf)。为了评估该方法的预测精度和预测能力,我们将Levenberg-Marquardt (lm)、BGFS准牛顿(bfg)和尺度共轭梯度(scg)三种不同的算法纳入该模型。通过对比实验结果和人工神经网络结果,验证了所生成的模型的正确性。采用R2和均方根误差(RMSE)值对算法的性能进行评价,结果表明,scg算法的性能最佳,R2为0.9655,RMSE为0.0223。人工神经网络模型的相对贡献图显示,填充压力的影响大于模具温度、填充时间和熔体温度。这些结果将为使用人工神经网络预测类似模塑部件的EDF奠定基础,并将有助于显著提高聚合物材料的脱模性能。
