  1. 21. Comparison of high-speed train market between Spain and Sweden. : Madrid-Barcelona vs Stockholm-Copenhagen.

    Master-uppsats, KTH/Trafik och logistik

    Författare :Marta Martínez cámara; [2011]
    Nyckelord :;

    Sammanfattning : In this work, several aspects have been studied and compared between Spain and Sweden in what respects to planned and existing High-Speed (HS) line, respectively: Stockholm- Malmö/Copenhagen and Madrid-Barcelona AVE. Population aspects have been studied with the result of a big difference between both corridors; however, it has been also found out that the impact of the lower populated Swedish cities along the corridor is not as negative as it is expected because of the regional and medium distance service that the new HS line will provide.

  3. 22. Traffic-induced vibrations on a two span composite railway bridge : Comparison of theory and measurements

    Master-uppsats, KTH/Bro- och stålbyggnad; KTH/Järnvägsgruppen, JVG

    Författare :José Miguel Escudero López; [2011]
    Nyckelord :High speed train; dynamic analysis; railway bridge; vibrations; Gröna Tåget; finite element model; eigenfrequencies; model updating;

    Sammanfattning : The economic and technologic development experienced by the society in the last decades has caused the demand of a new type of faster and more comfortable transport. This type of demand has been covered by the air transport, the road transport and the railway transport. LÄS MER

  4. 23. Traffic induced vibrations on a portal frame railway bridge : Comparison of theory and measurements

    Master-uppsats, KTH/Bro- och stålbyggnad; KTH/Järnvägsgruppen, JVG

    Författare :Andrea Llorens García; [2011]
    Nyckelord :Frame bridge; Dynamics; Support stiffness; High speed train; Ballast instability; Moving loads;

    Sammanfattning : The effect of different vertical support stiffness of a frame railway bridge is investigated in this study. Due to the dynamic loads of the high speed trains that run over the railway bridges, the response of these structures is far from the static effects. LÄS MER

  7. 25. Inventering av internationella bullerskyddsåtgärder för höghastighetståg

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Jonas Andersson; [2009]
    Nyckelord :Railway; noise; high-speed trains; noise preventive measures; Järnväg; buller; höghastighetståg; bullerskyddsåtgärder;

    Sammanfattning : Utvecklingen inom järnvägssektorn går mot snabbare och mer effektiva transporter, dock begränsas utvecklingen av att det krävs nya och mer utvecklade spår och tåg för att uppnå det. Med dagens infrastruktur och tågmodeller är hastigheter på 200 km/h det maximala. LÄS MER
