1. Simulation and Measurement of Wheel on Rail Fatigue and Wear
Sammanfattning : 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. LÄS MER
2. On Simulation of Uniform Wear and Profile Evolution in the Wheel - Rail Contact
Sammanfattning : 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. LÄS MER
3. On Efficient Modelling of Wheel-Rail Contact in Vehicle Dynamics Simulation
Sammanfattning : 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. LÄS MER
4. Wheel-rail contact modelling in vehicle dynamics simulation
Sammanfattning : The wheel-rail contact is at the core of all research related to vehicle-track interaction. This tiny interface governs the dynamic performance of rail vehicles through the loads it transmits and, like any high stress concentration zone, it is subjected to serious damage phenomena. LÄS MER
5. Inverse Identification of Dynamic Wheel-rail Contact Forces
Sammanfattning : Accurate evaluation of contact forces between wheel and rail is essential in the assessmentof vehicle performance and to predict consequences of dynamic vehicle-track interaction.As the contact forces can not be measured directly in the field, one common approachis to measure the strain or acceleration at various positions on a wheel or wheel axle.
