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

   Master-uppsats, KTH/Spårfordon

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

   Sammanfattning : 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. LÄS MER

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

   Master-uppsats, KTH/Spårfordon

   Författare :Adrián Sánchez Arandojo; [2013]
   Nyckelord :wear; code validation; GENSYS;

   Sammanfattning : 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. LÄS MER
