  2. 2. Influence of rail, wheel and track geometries on wheel and rail degradation

    Detta är en avhandling från Institutionen för farkostteknik

    Författare :Kalle Karttunen; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; track geometry; rolling contact; rail; railway; Rolling contact fatigue; maintenance; wear; wheel;

    Sammanfattning : For more efficient railway maintenance there is a need to increase the understanding of the influence of operational conditions on wheel and rail degradation. To this end, the chosen primary investigation strategy is to employ dynamic multibody simulations, where operational conditions are altered, to estimate the influence on material deterioration.

    Sammanfattning : Current and future requirements for efficiency force the automotive industry to consider all aspects of reducing the energy consumption of road going vehicles. An important aspect of reducing fuel consumption is reduced aerodynamic drag, which at highway cruising speeds is dominating the total drag force for both cars and heavy goods vehicles. LÄS MER

  5. 5. Simulation and Measurement of Wheel on Rail Fatigue and Wear

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Babette Dirks; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multibody simulations; prediction; wear; RCF; wheel; rail; cracks; measurements; Farkostteknik; Vehicle and Maritime Engineering;

    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
