1. 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
2. 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
3. Wheel–Rail Impact Loads and Track Settlement in Railway Crossings
Sammanfattning : Turnouts (Switches & Crossings, S&C) are critical components of a railway track requiring regular maintenance and generating high life cycle costs. A main driver for the high maintenance costs is the need to repair and replace switch rails and crossings as these components are subjected to a severe load environment. LÄS MER
4. Towards simulation-based optimisation of materials in railway crossings
Sammanfattning : Railway crossings are subjected to an intense load environment caused by the rail discontinuities needed to accommodate the passage of wheel flanges in intersecting traffic directions. This gives rise to high costs associated with repair and maintenance. LÄS MER
5. Modelling and laboratory investigations on freight wagon link suspensions with respect to vehicle-track dynamic interaction
Sammanfattning : The link suspension is the most prevailing suspension system for freight wagons in central and western Europe. The system design is simple and has existed for more than 100 years. However, still its characteristics are not fully understood. LÄS MER
