  1. 1. Data analytics and machine learning for railway track degradation: Using Bothnia Line track measurements for maintenance forecasting

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Elie Roudiere; [2024]
    Nyckelord :Railway; Track geometry; Machine learning; Statistics; Predictive maintenance; Botniabanan; Järnväg; spårgeometri; maskininlärning; statistik; förebyggande underhåll; Botniabanan;

    Sammanfattning : In this paper, a statistical method is developed to improve predictive maintenance on railway track. The problem tackled is being able to predict when the next maintenance event should take place to guarantee a certain track quality class. LÄS MER

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

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

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

    Sammanfattning : 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. LÄS MER

    Sammanfattning : The automotive industry has been involved in making vehicles autonomous to different levels in the past decade rapidly. Particularly in the commercial vehicle market, there is a significant necessity to make trucks have a certain level of automation to help reduce dependence on human efforts to drive. LÄS MER

  4. 4. Shock absorber dynamics : A parameter study of damper physical quantitiesand their effect on automobile comfort and control

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :David Stridfeldt; Jonsson Gustav; [2023]
    Nyckelord :Shock absorbers; dampers; parameter study; valve dynamics; comfort; control; Stötdämpare; dämpare; parameterstudie; ventildynamik; komfort; kontroll;

    Sammanfattning :   Damper performance is most commonly characterized by the damper’s forcevelocity behaviour. Different damper layouts and valving methods for creating oil flow constrictions bring different physical properties, outside of this conventional measure. LÄS MER

  5. 5. Design and Packaging of All-in-One Axle

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Alafiya Talib; Lakshay Singhal; [2023]
    Nyckelord :E-axle; Modularity; PUGH’s Matrix; CAD-Modeling; Kinematic Analysis; Finite Element Analysis; E-axel; Modularitet; PUGHs matris; CAD-modellering; Kinematisk Analys; Finita Element Analys;

    Sammanfattning : The aim of this thesis work is to design an electric axle that contains all the operational components, like the powertrain, suspension, brakes, and steering system. One of the requirements of this design work is to package all the axle components compactly in one single unit. LÄS MER
