Paper Title:
Researches on Rules of the Longitudinal Residual Stress Distribution in Straightening Deformation Zone of Heavy Rail with Multi-Rollers
  Abstract

The paper simulated and researched the straightening process of heavy rail by finite element software of ANSYS/LS-DYNA. The residual stress of the rail head, rail base, rail loin in the 7th deformation zone meets the real straightening condition in the straightening simulation. The calculation indicates: The residual stress of the rail head, rail base, rail loin in various deformation zones varies significantly like the variation of tensile-compression-tensile. Compared with the on-site rule, the residual stress of rail base decreased155 Mpa, this is in agreement with the values of practice.
