【Abstract】 Based on the improved BP neural network, four models of 7 parameters and 5 parameters with regard to the maximum contraction length and the contraction area are established by using experiment data of practical ship plate bending by line heating. The network structure and the training process are explained, and the error resulted from the models is discussed.更多还原
