Abstract
High strength steel is widely used in the manufacturing of parts dealing with heavy cyclic loads and corrosive environments. But to obtain accurate final shapes for this type of steel by roll bending process is not easy. And it becomes a hard-to-solve problem when the part to produce is large, thick and unrepeated. In order to analyse the dynamic deformation of the workpiece during the roll bending process, Finite Element Method (FEM)?Ansys/LS-Dyna is introduced to do this research. Various dynamic simulations based on 3D element models are performed to provide better understanding of whole deformation history and distribution of stress-strain of the workpiece during this particular process. The results from FE simulation are then compared with corresponding experiment results from an industrial roll bending machine.
