1. Influence of rail, wheel and track geometries on wheel and rail degradation
Abstract : For more efficient railway maintenance there is a need to increase the understanding of the influence of operational conditions on wheel and rail degradation. To this end, the chosen primary investigation strategy is to employ dynamic multibody simulations, where operational conditions are altered, to estimate the influence on material deterioration.

3. Simulation and Measurement of Wheel on Rail Fatigue and Wear
Abstract : The life of railway wheels and rails has been decreasing in recent years. This is mainly caused by more traffic and running at higher vehicle speed. READ MORE

4. On Simulation of Uniform Wear and Profile Evolution in the Wheel - Rail Contact
Abstract : Numerical procedures for reliable wheel and rail wear prediction are rare. Recent development of simulation techniques and computer power together with tribological knowledge do however suggest computer aided wear prediction as possible. READ MORE

5. On Efficient Modelling of Wheel-Rail Contact in Vehicle Dynamics Simulation
Abstract : The wheel-rail contact is at the core of all research related to vehicletrackinteraction. This tiny interface governs the dynamic performanceof rail vehicles through the forces it transmits and, like any high stressconcentration zone, it is subjected to serious damage phenomena. READ MORE
