FEM Simulation of Cold Roll Forming in the Car crash beam

摘要：

The cold roll forming process of cars rubbing beam was simulated by MSC.Marc. The history-curves of the stress and strain of the special node were obtained and the deformations of the transition zone were analyzed. The simulation results show that as the metal sheet is bending, deformation changed from the elastic to plastic deformation, in each pass, the bending stress increased, then decreased, and after some fluctuation it tends to a steady state, from this point of view, Cold Roll Forming is a multiple loading and unloading process.
