| Abstract: | There are many factors influencing the springback of V shape bending parts,such as workpiece size,mechanical properties and loading conditions,which interact with each other,representing highly complicated non-linear.The bending angle and radius were taken as two objective functions.A SVM model was constructed to deploy to the sequential forward select algorithm.Thus an optimal feature subset was selected with high efficiency.Comparative experimental results with FEM and actual experiment validate the feasibility of the proposed model. |
