Application of network and orthgonal experiment method in optimization of sheet metal forming process technology

SU Juan-hua1,ZHANG Wen-qiong1,LI Li-chun2(1.School of Materials Science and Engineering,Henan University of Science and Technology,Luoyang 471003,China;2.YITUO(Luoyang) Flag Auto-Body Co.,Ltd.,Luoyang 471003,China)  
The data got from an orthogonal experiment was used as the training sample to establish a neural network model in which the input was the technological parameters and the output was the springback quantity.The accuracy of the ANN model was proved by the sample.In this way,the time to set the technological parameters was shortened.The ANN model was used to substitute CAE numerical simulation test,and combined with orthogonal experiment method,the technological parameters was further optimized.The result shows that the integration of ANN,orthogonal experiment and numerical simulation method used in optimization of sheet metal forming has shorten the time of technological parameter optimizing and has greatly increased the technological design efficiency.
