1. 1. Vehicle dynamics modelling of electromagnetic suspensions for MAGLEV applications

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

   Author : Léa Chatelais; [2024]
   Keywords : MAGLEV; Dynamics; Requirements; Suspension; Vehicle modeling; MATLAB; MAGLEV; Dynamisk; Fordran; Upphängning; Fordon modell; MATLAB;

   Abstract : MAGnetic LEVitation Guidance System (MAGLEV) technology was commercially introduced relatively recently in the guided transport field. It is based on removing the wheels and rails of classic railway systems and supporting and guiding the train with magnets and magnetic forces instead. READ MORE

3. 2. Numerical modelling of high-speed railway transition zone

   University essay from KTH/Jord- och bergmekanik

   Author : Karl Norberg; [2022]
   Keywords : Railway geotechnics; Bridge; Ballastless track; Transition zone; High-speed railway; Finite element method; Track stiffness;

   Abstract : Transition zones are changes in the track structure, detected by an abrupt deviationin track stiffness and/or differential settlements. One inevitable transition zone is thebridge approach. This study has investigated in this transition zone, adapted for highspeed,ballastless track. READ MORE

4. 3. Parametric Studies of Train-Track-Bridge Interaction : An evaluation of the dynamic amplification due to track irregularities for freight transport

   University essay from KTH/Bro- och stålbyggnad

   Author : Rasmus Elm Dahlman; Emil Lundberg; [2021]
   Keywords : Dynamics; dynamic amplification factor; railway bridge; train-track-bridge interaction; vehicle model; track irregularities; PSD; Dynamisk förstoringsfaktor; dynamik; järnvägsbroar; tåg-spår-bro interaktion; fordonsmodell; spårojämnheter; PSD;

   Abstract : In this thesis a train-track-bridge interaction (TTBI) model is developed in order to study the dynamic amplification from track irregularities on railway bridges traversed by freight trains. These simulations are of great importance since rail freight transport is expected to increase in order to meet the climate goals. READ MORE

5. 4. Life Cycle Cost of Smart Wayside Object Controller

   University essay from KTH/Spårfordon

   Author : Filipp Zarov; [2021]
   Keywords : railway signalling system; interlocking; hardware; Object Controller; Smart Wayside Object controller; Lifecycle Cost; renewable energy sources; järnvägssignalsystem; ställverk; hårdvara; Utdelar; SWOC; livscykelkostnad; förnybara energikällor;

   Abstract : In a regional railway signalling system, object controllers are the devices responsible for controlling Track Side Equipment and act as interfaces for TSE with the interlocking computer and the Traffic control system. However, associated cabling (signal and power cabling) and civil works pose a major capital investment and it is a source of significant Capital and Operational expenses, particularly in rural areas, where accessibility andconnectivity to power grid and to the interlocking are a problem.

6. 5. The Resilience of the Rail System for International Freight in Öresund Region in Case of Major Disruptions

   University essay from KTH/Transportplanering

   Author : Sneha Gosavi; [2021]
   Keywords : Öresund Fixed Link; Capacity constraints; Freight trains; Simulation; Fast förbindelse Öresund; Kapacitetsbegränsningar; godståg; simulering iv;

   Abstract : Rail Transport has held an important place in the European economy. Several problems plague rail freight. We frequently hear about train disruptions, whether it is due to a signal failure or an infrastructure breakdown, most of which have caused significant issues for both passengers and cargo. READ MORE
