The regularity of bending of 100 m U75V steel straight rail during cooling process before straightening has been calculated by analyzing the boundary conditions of cooling of 100 m rail and using three-dimensional instantaneous non-linear finite element method. Results show that the bending deformation of the straight steel rail during cooling process is a repeat-cycling process
but the rail eventually is bent to the rail head ; with considering the friction between steel rail and cooling bed
after the straight steel rail finishing cooling the deforming feature of rail is straight at middle part
bent at both ends and scope of bent ends covering 18 m.
