Notes:
The paper simulated and researched the straightening process of heavy rail by finiteelement software of ANSYS/LS-DYNA. The residual stress of the rail head, rail base, rail loin in the7th deformation zone meets the real straightening condition in the straightening simulation. Thecalculation indicates: The residual stress of the rail head, rail base, rail loin in various deformationzones varies significantly like the variation of tensile-compression-tensile. Compared with the on-siterule, the residual stress of rail base decreased155 Mpa, this is in agreement with the values of practice
