The Simulation Analysis of Tension Leveling for Improving the Shape Defects of Strip

Abstract:

According to the computation model of the stress, the strain, and the extend ratio in tension leveling, under the platform of mat lab, take the linear strengthening ball plastic model as the foundation, established the simulated program of the quantitative parameters enactment of tension leveling craft, this procedure consideration initial remaining stress of strip, namely random shape defects, assign tensile stress and the curving curvature, compute the strip’s stress and strain change and elongation ratio after tension leveling, given the stress and strain and the extension rate of the main process parameters from the simulation results of each roller, analysis of different process parameters set on impact of the simulation results, and the results conform to reality tension leveling production.
