摘要:
为了更加快捷方便的获得X80管线钢管环焊缝焊接接头抗拉强度,通过IPOA-BP算法构建了X80管线钢管环焊缝焊接接头抗拉强度预测模型,引入Logistic混沌映射、反向差分进化和萤火虫算法来提高POA算法的寻优能力。模型选择焊接电流、焊接电压、焊接热输入、保护气体流量、焊接速度、送丝速度作为焊接工艺输入参数,接头抗拉强度作为输出参数。把IPOA-BP模型和POA-BP模型以及BP神经网络模型进行对比,通过训练集对模型进行训练、测试集对模型进行验证,用均方误差、平均绝对百分比误差和R?来评价模型。最终结果表明,IPOA-BP算法模型预测更加精准,拟合程度更高。
Abstract:
In order to obtain the tensile strength of X80 pipeline steel girth weld joints more quickly and conveniently, a prediction model for the tensile strength of X80 pipeline steel girth weld joints was constructed using the IPOA-BP algorithm. Logistic chaotic mapping, reverse differential evolution, and firefly algorithm were introduced to improve the optimization ability of the POA algorithm. The model takes welding current, welding voltage, welding heat input, shielding gas flow, welding speed, wire feed speed as input parameters, and joint tensile strength as output parameters. The IPOA-BP model, POA-BP model and BP neural network model are compared. The training set is used to train the model, and the test set is used to verify the model. The mean square error, mean absolute percentage error and R? are used to evaluate the model.The final results show that the IPOA-BP algorithm model is more accurate and has a higher degree of fitting.
