  1. 11. Influence of Switches and Crossings on Wheel Wear of a Freight Vehicle

    University essay from KTH/Spårfordon

    Author : Emmanouil Doulgerakis; [2013]
    Keywords : dynamic vehicle-track interaction; turnout; switch crossing; wheel wear; wheel-rail contact geometry;

    Abstract : Turnouts (Switches & Crossings) are important components in railway networks, as they provide the necessary flexibility for train operations by allowing trains to change among the tracks. But the turnout’s geometry with discontinuity in rail profiles and lack of transition curve causes additional wear both on track and on vehicle. READ MORE

  3. 12. On validation of a wheel-rail wear prediction code

    University essay from KTH/Spårfordon

    Author : Adrián Sánchez Arandojo; [2013]
    Keywords : wear; code validation; GENSYS;

    Abstract : During the past years, several tools have been developed to try predicting wheel and rail wear of railway vehicles in an e-cient way. In this MSc thesis a new wear prediction tool developed by I.Persson is studied and compared with another wear prediction tool, developed by T. READ MORE

  4. 13. Algorithm for Estimation of Wheel-Rail Friction Coefficient from Vehicle-Track Forces

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Vladislav Petrov; [2012]
    Keywords : wheel-rail friction; friction coefficient; estimation of friction; contact point; vehicle simulation; vehicle certification;

    Abstract : In order to ensure safe travel, railway vehicles must be stable under every condition along the track. Thus, a vehicle can be certified for operation only when it can fulfil certain criteria related to the ride stability. The stability of the vehicle is highly dependent on the wheel-rail friction coefficient: higher friction results in worse ride. READ MORE

  5. 14. Wheel Wear Simulation of the Light Rail Vehicle A32

    University essay from KTH/Spårfordon

    Author : Ignacio Robla Sánchez; [2010]
    Keywords : wheel wear; light rail; train; simulation; vehicle model; wear chart; wheel flange; tread; rail profile; wheel profile.;

    Abstract : During the last decade, a novel methodology for wheel wear simulation has been developed in Sweden. The practical objective of this simulation procedure is to provide an integratedengineering tool to support rail vehicle design with respect to wheel wear performance and detailed understanding of wheel-rail interaction.

  6. 15. Simulation of Rail Wear on the Swedish Light Rail Line Tvärbanan

    University essay from KTH/Spårfordon

    Author : Anneli Orvnäs; [2005]
    Keywords : rail wear; simulations;

    Abstract : Rail wear can result in extensive costs for the track owner if it is not predicted and preventedin an efficient way. To limit these costs, one measure is to predict rail wear through wear simulations. READ MORE
