  1. 1. Simulation of Wheel and Rail Profile Evolution Wear Modelling and Validation

    Detta är en avhandling från Stockholm : KTH

    Författare :Roger Enblom; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; contact; wear; wear prediction; wear model; wheel profile; rail profile; simulation vehicle-track interaction; multibody simulation; MBS; TECHNOLOGY; TEKNIKVETENSKAP;

    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

  2. 2. Ride Comfort Optimization of Buses

    Detta är en avhandling från Stockholm : KTH

    Författare :Peter Eriksson; [2002]

  4. 4. Wheel-rail contact modelling in vehicle dynamics simulation

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

    Författare :Matin Shahzamanian Sichani; Mats Berg; Roger Enblom; Elena Kabo; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheel-rail contact; non-elliptic contact; vehicle-track interaction; rail vehicle dynamics; rolling contact; MBS; virtual penetration; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology;

    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
