| Abstract: | In order to obtain the accurate numerical solution, the finite element calculation is made on the wheel-rail contact stress with the application of the elastoplastic theory and the large finite element software ANSYS, in the mean time, the calculation process of the model establishment,cell selection, grid classification and parameter determination, etc. are described, the wheel-rail plastic district dimensions, the contact spot shapes, the maximum Mises equivalent stresses under different axle-loads (1 t~30 t) as well as the changing law of the wheel-rail contact pressure stresses along with the axle-loads are obtained. |
