1. 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

3. On Heavy-Haul Wheel Damages using Vehicle Dynamics Simulation
Sammanfattning : Maintenance cost is one of the important issues in railway heavy-haul operations. In most of the cases, these costs are majorly referring to reprofiling and changing the wheels of the locomotives and the wagons. The main reason of the wheel damages is usually severe wear and/or surface initiated rolling contact fatigue (RCF). LÄS MER
