| Abstract: | The paper aims to study the springback deformation characteristics of a complex side rail under front floor made from High Strength Steel (HSS) and seek measures for springback control. CAE analysis technology was employed to simulate whole forming processes and predict springback. Springback features and influence factors were discussed. Several springback control measures were proposed. By application of springback control measures, the size accuracy of specimen reached the quality requirement of 1mm. The average qualified rate reached 90%. The requirement on quality of sample product was met. Numerical simulation analysis can predict formability and springback of parts and provide useful reference to process design and mold development. Springback control measures proposed in this paper can be used to guide mold development of other similar parts. |
