The Modification of Leveling Model for Roller Leveler Based on Ansys/LS-DYNA

Abstract:

The paper researched a seven-roll leveler in the cross cut shearing line of a factory. An analytical model of the roller intermesh was established based on the elastic-plastic bend theory. It was known the maximal deformation of strip happened on the second leveler roll in the leveling process by the analysis of FEM simulation for the calculation results of analytical model. However, the restriction applied to the strip at the entrance side was smaller than expected, which caused the deformation was smaller than the calculated value of analytical model. Aiming at this program, combined with the analysis of FEM simulation, it was improved by adding the adjustment of the intermesh of first roll.
