6. Simulation of Wheel and Rail Profile Evolution : Wear Modelling and Validation
Sammanfattning : Numerical procedures for reliable wheel and rail wearprediction are rare. Recent development of simulationtechniques and computer power together with tribologicalknowledge do however suggest computer aided wear prediction. LÄS MER
7. 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
8. Time-domain modelling of curve squeal: a fast model for one- and two-point wheel/rail contact
Sammanfattning : Curve squeal is a type of railway noise that may arise when a railway vehicle negotiates a relatively tight curve. A single frequency, corresponding to a wheel mode, dominates the radiated sound, which makes squeal a very tonal noise. LÄS MER
9. Modelling of Dynamic Contact - Exemplified on the Tyre/Road Interaction
Sammanfattning : Noise is a severe problem in modern society. Road traffic noise is a substantial contributor and the tyre/road interaction is the main noise source for normal driving conditions. Despite more than 30 years of research, there is a lack of quantitative tyre/road noise prediction models. LÄS MER
