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.
