Al-Cu-Mg-Ag合金强度性能的支持向量回归预测
Strength Prediction for Al-Cu-Mg-Ag Alloy Based on Support Vector Regression
摘要
Abstract
To explore the strength properties of Al-Cu-Mg-Ag alloy at different aging temperature and aging time, the support vector regression (SVR) approach combined with particle swarm optimization (PSO) algorithm was proposed to construct a SVR model based on experimental data. In the modeling process, the aging temperature and aging time were employed as input parameters, the tensile strength and yield strength acted as outputs. By comparison with BP neural network, it was found that the prediction accuracy of the established SVR model was higher than that of BPNN model by applying identical training and test samples. This investigation would provide a theoretical foundation for further study on the effect of aging condition on mechanical property, and the optimal design of the aging process for fabricating Al-Cu-Mg-Ag alloy.关键词
