  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. Parameter study for an energy efficient suspension for a rail vehicle prototype

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Ludvig Danström; [2023]
    Keywords : Delsbo electric; Energy efficiency; Rail vehicle; Suspension system; Delsbo electric; energieffektivitet; fjärder- och dämparsystem; spårfordon;

    Abstract : The push for sustainability in all parts of our society has never been as big as it is currently. One project that aims to produce sustainable innovation in the railway industry is the Delsbo Electric competition where some of the world’s most energy efficient vehicles compete. READ MORE

  4. 3. Cybersecurity in Railways : Identifying and Communicating Risks using System Dynamics Modeling

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Cecilia Mikiver; [2022]
    Keywords : System dynamics; System Dynamics Modeling; CLD; Cybersecurity; Safety; Railway; Digitalization.; Systemdynamik; Systemdynamisk Modellering; CLD; Cybersäkerhet; Säkerhet; Järnväg; Digitalisering;

    Abstract : Extensive digitization is currently underway in the railway sector, which has resulted in several benefits and improvements, but also challenges. The increased use of digital technologies increases the risks of vulnerabilities and susceptibility to cyberattacks. READ MORE

  5. 4. 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

  6. 5. Dynamic Simulation and Suspension Optimization for a Heavy Duty Railway Bogie

    University essay from KTH/Spårfordon

    Author : David Prifer; [2021]
    Keywords : Rail vehicle; Bogie Technology; Running Dynamics; Simulation; Simpack; Vehicle Acceptance; Validation; Järnväg; Gångegenskaper; Flerkroppssimulering; Acceptanskrav;

    Abstract : A multi-body simulation study was undertaken to investigate the running behavior of a rail grinder vehicle with newly developed Ganz bogies. The main purpose of the simulations was to forecast and support the vehicle acceptance tests and support the ongoing development. READ MORE
