The Numerical Simulation Analysis of the Straightening Process of the Large H-Shaped Steel

Abstract:

A solid model and finite element model of nine-roller constant roller spacing of large H-shaped steel were set up, researching the problems of elastic-plastic deformation in straightening simulation for nine rollers continuous straightening process of large H-shaped steel. Through analyzing the stress and strain relation of large H-shaped steel, and analyzing the residual stress of H-shaped steel in the straightening process, a theoretical basis for the further step analysis the residual stress control after the H-shaped steel straightening was established.
