Researches on rules of the longitudinal residual stress distribution in straightening deformation zone of heavy rail with multi-rollers

摘要：

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 meet the real straightening condition in the straightening simulation. The calculation indicates: The residual stress of the railhead、rail base、rail loin in various deformation zone vary significantly like the variation of tensile-compression-tensile.
