   Sammanfattning : El objetivo de la presente tesis es la mejora de los actuales ejes de ancho variable para su circulación por vías de alta velocidad (AV) a velocidades de hasta 300km/h. En la actualidad los vehículos con ejes de ancho variable no sobrepasan los 250km/h de velocidad de servicio en vías de AV, lo que supone un claro desaprovechamiento de recursos y dificultades de gestión del tráfico para el gestor de la infraestructura a causa de las distintas velocidades punta de los diferentes trenes.

4. 3. Vehicle Conceptualisation, Compactness, and Subsystem Interaction : A network approach to design and analyse the complex interdependencies in vehicles

   Författare :Sai Kausik Abburu; Carlos Casanueva; Ciarán J. O'Reilly; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Subsystem interaction; Interaction effects; Design Structure Matrix; Network theory; Cross-scalar design tool; Induction motor; Inverter.; Farkostteknik; Vehicle and Maritime Engineering;

   Sammanfattning : The conventional approach to vehicle design is restrictive, limited, andbiased. This often leads to sub-optimal utilisation of vehicle capabilities and allocated resources and ultimately entails the repercussions of designing andlater on an using an inefficient vehicle. LÄS MER

5. 4. On Heavy-Haul Wheel Damages using Vehicle Dynamics Simulation

   Författare :Saeed Hossein Nia; Sebastian Stichel; Carlos Casanueva; Per-Anders Jönsson; Ernesto Garcia Vadillo; KTH; []
   Nyckelord :wear; RCF; rolling contact; traction; braking; heavy-haul; FASTSIM; FaStrip; Vehicle and Maritime Engineering; Farkostteknik;

   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

   Sammanfattning : Track damage due to progressively increasing tonnage, especially due to longer and heavier freight trains, is one of the major problems faced in the European rail sector. In this context, to stay competitive, optimal track maintenance practices, track-friendly vehicles and safe operations of long freight trains assume prominence. LÄS MER
