FEM Simulation and Analysis of Variable Parameters for the Three-Roll Cylindrical Bending of Plate Process
A three-dimensional model is developed to study the dynamic process of three-roll plate bending using finite element method (FEM). In this work, the continuous three-roll bending configuration with cylindrical rolls is used to bend a thick plate into a cylindrical shape. It presents the geometrical setup and the finite element model. This 3D simulation is based on the elastic plastic explicit dynamic FEM under the ANSYS/LS-DYNA environment. Effect of initial strain and change of material properties during deformation is neglected. In order to investigate the influence of parameters on the process, top roller position, friction between rolls and plate, and temperature are also discussed. It is found that the simulation program is a feasible and economical method to study the influence of these parameters, and the FEM simulation can also provide engineers with a convenient analytical tool for optimizing process parameters.
