  1. 6. System Stability of the Overhead Power Supply System used in the Electric Road System

    Master-uppsats,

    Författare :Md Asif Ferdoush; [2019]
    Nyckelord :Electric Road System; eHighway; eMachine; Power Electronics; Overhead Catenary Line; Pantograph; Harmonics; Resonance;

    Sammanfattning : This thesis presents the stability analysis of an Electric Road System (ERS), which is often abbreviated as eHighway, used for the electrification of the hybrid vehicle. The overall system modelling of the ERS, starting from the sub-station to the critical part of the Scania hybrid truck is performed in the MATLAB Simulink environment. LÄS MER

  3. 7. Attraktiv stad med spårväg - En litteraturstudie

    Kandidat-uppsats, Lunds universitet

    Författare :Olle Karlsson; [2018]
    Nyckelord :spårväg; stadsplanering; attraktiv stad; attraktiv stadsmiljö; Technology and Engineering;

    Sammanfattning : Internationally there has been a growing interest of tramways the past decades. Swedish cities have taken notice of the positive characteristics that tramway have on cities and many of them has also begun investigations for future projects including tramway. LÄS MER

  4. 8. Integrated analysis and design using graphic statics

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Erik Larsen; [2017]
    Nyckelord :Graphic statics; integrated design; sustainability; computational design; gaussian vault; catenary line; structural exploration; Technology and Engineering;

    Sammanfattning : Numerical methods are the norm in modern structural engineering practice Models based on elasticity theory offer powerful methods to analyse complex structural behaviours and accurately predict probable deformation behaviour. Numerical methods in general and particularly finite element methods offer great numerical accuracy. LÄS MER

  5. 9. Mekaniska kopplingar med hög deformationskapacitet för stommar byggda av prefabricerade betongelement

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Konstruktionsteknik

    Författare :Tobias Eriksson; John Fritz; [2016]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Precast concrete structures has no natural coherence of the frame as when the structure is cast in situ, which puts great demands on the ties between the prefabricated concrete elements regarding the resistance and deformation capacity. The ties that are used today often consist of straight ribbed bars embedded in concrete and therefore have limited deformation capacity. LÄS MER

  7. 10. Kontaktledningsavspänning - En jämförelse mellan fast och rörlig avspänning i spårvägsmiljö

    Kandidat-uppsats, Lunds universitet/LTH Ingenjörshögskolan vid Campus Helsingborg

    Författare :Mattias Dalstål; Timothy Jannas; [2016]
    Nyckelord :spårväg; spårvagn; avspänning; kontaktledning; underhåll. tramway; tram; overhead line; tensioning; maintenance; Technology and Engineering;

    Sammanfattning : By initiative from Sweco Rail, we have made a comparison between fixed and automatic tensioning devices for tramways to determine when there is an advantage to choosing an automatic device instead of a fixed solution. Main focus has been tramways in city environment, with extra focus on Gothenburg. LÄS MER
