  1. 16. Load-carrying capacity of a strengthened reinforced concrete bridge : Non-linear finite element modeling of a test to failure. Assessment of train load capacity of a two span railway trough bridge in Örnsköldsvik strengthened with bars of Carbon Fibre Reinforced Polymers (CFRP)

    Författare :Arto Puurula; Mario Plos; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : To meet the future traffic demands there is a constant need of making the infrastructure moreeffective. This can be achieved by increasing the capacity and/or life length of traffic lines. LÄS MER

  3. 17. Styrning av tågtrafik på Malmbanan

    Författare :Kristina Nilsson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell logistik; Industrial Logistics;

    Sammanfattning : The single-track Swedish iron ore line Malmbanan stretches from Luleå to the Norwegian city of Narvik. The mine company LKAB transport iron ore on Malmbanan from the mines in Kiruna and Malmberget to the harbours in Narvik and Luleå for export. The daily traffic also consists of passenger trains and freight trains. LÄS MER

  4. 18. Regional Intermodal Transport Systems : Analysis and Case Study in the Stockholm-Mälaren Region

    Författare :Behzad Kordnejad; Bo-Lennart Nelldal; Rickard Bergqvist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för godstrafik;

    Sammanfattning : The global trend of urbanization is evident and also valid in Sweden and for the Stockholm-Mälaren region, also referred to as the Mälaren valley, a region consisting of metropolitan Stockholm and areas around the lake of Mälaren. In this context, efficient urban freight transportation has emerged as essential for sustainable development of urban areas. LÄS MER

  5. 19. Train–Bridge Interaction : Literature Review and Parameter Screening

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamics; vibration; railway bridge; bridge deck acceleration; moving load; train–bridge interaction; vehicle model; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : New railway lines are continuously being constructed and existing lines are upgraded. Hence, there is a need for research directed towards efficient design of the supporting structures. LÄS MER

  7. 20. Simulation of rail traffic : applications with timetable construction and delay modelling

    Författare :Hans Sipilä; Bo-Lennart Nelldal; Anders Holst; Jan Ekman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis covers both applications where simulation is used on parts of the Swedish rail networks and running time calculations for future high-speed trains with top speed improvements on existing lines. Calculations are part of a subproject within the Green Train research program (Gröna tåget). LÄS MER
