The FE Simulation Research on Roll Bending Process of Complex Sheet with Padding Assisted

摘要：

　　The roll bending process with padding assisted is a new profile forming method.In this paper,the aluminum sheet 2024-T3 with variable thickness is roll bended through three-roller with padding assisted.The finite element model is established with ABAQUS software,the forming process and springback are successfully simulated.The padding material and the padding thickness are discussed based on FE model.The result showed that the PA6-G,with a higher strength,is a preferred padding material.The good forming result will be obtained if the padding of thicker thickness is chosen among 6mm and 9mm.This research provides some useful references for the real forming process of complex sheet.
