1. 1. Verication of simulated wheel-rail forces with measured data

   University essay from KTH/Spårfordon

   Author : Marcus Jans Bertilsson; [2015]
   Keywords : ;

   Abstract : The purpose of this thesis was to verify the simulated wheel-rail forces from the simulation soft-ware Simpack by comparing the results with on-track measurements. The report constitutes a literature study on wheel-rail contact modelling and techniques for measurements of track forces and track irregularities. READ MORE

3. 2. Investigation of Causes for Wheel Squeal on Roslagsbanan in Stockholm

   University essay from KTH/Spårfordon

   Author : Zhan Ouyang; [2014]
   Keywords : ;

   Abstract : The purpose of this work is to investigate the possible causes of wheel squeal on Roslagsbanan, a narrow gauge (891mm) suburban railway system in Stockholm, Sweden. Simulation of the dynamic behaviour of vehicles negotiating curves was carried out by means of the Swedish multibody simulation software GENSYS [1]. READ MORE

4. 3. 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

5. 4. 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

6. 5. 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.
