Thermoelastic Stresses Due to Wheel-Rail Contact in Pure Sliding State

  • Received Date: 04 Jan 2007

  • A finite element method was applied to establish a thermal-mechanical coupling model for wheel-rail contact in pure sliding state.The non-steady heat conduction between the contacting surfaces of wheel-rail,heat-convection and radiation between the wheel-rail and the ambient were considered.Analysis emphases were put on thermal and stress fields in the expansion process of contact patch due to wear of pure sliding,the effect of expansion rate of contact patch on thermoelastic stresses,and on failure locations of wheel-rail under the thermal-mechanical loads.Calculation results show the expansion of the contact patch significantly affects temperature and stress distributions,and the planes of maximum shear stress and shear strain are at angles about 50° and 140° with respect to the sliding direction.
