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

    Author : Roger Enblom; KTH; []
    Keywords : contact; wear; wear prediction; wear model; wheel profile; rail profile; simulation vehicle-track interaction; multibody simulation; MBS; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : 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. READ MORE

    Abstract : Numerical procedures for reliable wheel and rail wear prediction are rare. Recent development of simulation techniques and computer power together with tribological knowledge do however suggest computer aided wear prediction as possible. READ MORE

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

    Author : Babette Dirks; Mats Berg; Roger Enblom; Mark Burstow; KTH; []
    Keywords : multibody simulations; prediction; wear; RCF; wheel; rail; cracks; measurements; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : 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. READ MORE

  6. 4. On Efficient Modelling of Wheel-Rail Contact in Vehicle Dynamics Simulation

    Author : Matin Shahzamanian Sichani; Mats Berg; Roger Enblom; Asier Alonso; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheel-rail contact; non-elliptic contact; rail vehicle dynamics; rolling contact; vehicle-track interaction; wheel-rail damage; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : 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.
