   Keywords : Multi-body simulations; wheel damages; rail damage; damage thresholds; wheel-rail impact forces; classification; Flerkroppssimulering; hjulskador; rälskador; skadetrösklar; hjulslagkraft; rälslagkraft; klassificering;

   Abstract : Due to the increase in demand on freight transportation it becomes necessary to avoid delays to ensure that the goods reach its destination on time. The main factors causing disturbances in the traffic on the mainline is the breakdown of vehicles mainly due to damaged wheels. READ MORE

3. 2. 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

4. 3. High frequency vehicle-track interactionsimulation : Coupling of an advanced track model with a multi-bodysystem

   University essay from KTH/Järnvägsteknik

   Author : Pierre Gely; [2014]
   Keywords : ;

   Abstract : The forces caused by the high frequency vehicle-track interaction have a great impact on thetrack maintenance. They should be represented in vehicle-track models in order to predicttheir impact. As a result, a multi-body system (MBS) should be extended with an advancedtrack model. READ MORE
