Abstract:
The wheel/rail contact is a critical component of the rail vehicle system, which is a problem of considerable complexity, both from the perspective of the physical interpretation and the mathematical formulation. This explains why the modelling of wheel/rail contact is still a key research topic worldwide for several decades for scientists and engineers aiming at developing more accurate and efficient formulations to meet the demand of engineering applications. This talk shares our contributions to the state of the art and my views on the future development in this field following the evolution of the wheel/rail contact modelling from Hertzian to non-Hertzian and non-conformal to conformal contact.
