摘要：

The deformation of roll forming is very complicated and shows obvious material nonlinearity, geometric nonlinearity and boundary nonlinearity. The simulation of roll forming with multiple passes was studied by FEM software ABAQUS. Based on dynamic explicit algorithm and using approach that the metal sheet is pulled by leading sheet, an FE model of roll forming with multiple passes is set up. The key problems in the model, model construction, choosing element, boundary condition, virtual speed of metal sheet, loading amplitude and springback are discussed, and a simulation method for roll forming with multiple passes is proposed. The method is validated with roll forming process with 12 passes of channel section with outer edge.
