| Abstract: | According to different deformation rates in various parts of rail head after rail straightening,stress and bending moment were analyzed in the process of rail straightening by means of the mechanics of materials and elasticity.Meanwhile the result of simulation test on three-point bending of rail in laboratory was discussed and the initial reasons of inhomogeneous deformation of rail head and surface deformation in the process of rail straightening had been found out. |

| Keywords: | rail straightening deformation stress elastic-plastic bending bending moment |
