| Abstract: | ANSYS FEM is used to solve the elastic and static wheel-rail contact problem. The real geometry and edge conditions of wheel-rail are simulated and the influence of different wheel diameters, different axle loads and the sleeper supporting on the different of wheel set on contact elastic-plastic stress/strain are studied. The paper shows that the most important factor is the lateral shift. |
