Study on the Temperature Changing Rules of U75 V Rail in the Cooling Process

Abstract Caused by the differences in volume and heat dissipation area of rail head and bottom, latent heat of phase transition releasing and other reasons, the complicated temperature changes occurs in rail head and bottom between during the cooling process, especially in solid state phase transition. In the paper, the ANSYS heat-stress couple module is adopted to carry on numerical simulation on the cooling process of 60 kg/m U75 V heavy rail. Though the post-processing result analyzed by using the post-processor module, we got the temperature changing rules for heavy rail cooling process. This paper is of great reference value for the bending deformation study in the hundred-meter heavy rail cooling processing.
