Abstract:The common defection of the plate was analyzed. Mathematical models of improving the stresses were researched and the process of solving the models was given. The 3D contact element model was built and simulated to check whether the mathematical models were correct or not. There was a good consistency when comparing the residual stress distribution by FEM with analysis models after levelling. The regulation and laws of improving the residual stresses in width direction of the plate were researched and the strategy of controlling residual stress after levelling were proposed based on the mathematical model. The research result shows that the residual stress can be improved well when the roller gap increases and the plastic radio should be controlled between 70% and 80%.
