| Abstract: | The simulation of roll forming with multiple passes was studied by FEM software ABAQUS. Research has been made aiming at forming technic and forming rules. Based on the simulation results the potential problems in the process have been forecasted and analyzed quantitatively . The multi-pass roll forming of air duct flange was simulated with the dynamic explicit finite element method. General problem on roll forming such as model construction, choosing element, boundary condition, virtual speed, mass scaling factor are discussed. |
