  1. 1. 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

  3. 2. Condition monitoring of railway vehicles : a study on wheel condition for heavy haul rolling stock

    Författare :Mikael Palo; Thomas Robertsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : A railway is an energy efficient mode of transport as it uses the low resistance contact between wheel and rail. This contact is not frictionless and causes wear on both surfaces. The wheel-rail guidance is made possible by the shapes of wheel and rail profiles. LÄS MER

  4. 3. Riksgränsbanans elektrifiering : Stat och företag i samverkan: 1910-1917

    Författare :Roine Wiklund; Mats Fridlund; Luleå tekniska universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Teknikhistoria; History of Technology;

    Sammanfattning : Syftet med föreliggande doktorsavhandling i teknikhistoria är att öka kunskapen om varför, men framförallt hur och under vilka villkor den första elektrifieringen av en statsägd järnväg genomfördes i Sverige. Arbetet med Riksgränsbanans elektrifiering pågick 1908-1917 och var på många sätt ett unikt pionjärprojekt. LÄS MER

  5. 4. An Investigation of the Iron-Ore Wheel Damages using Vehicle Dynamics Simulation

    Författare :Saeed Hossein Nia; Sebastian Stichel; Matti Rantatalo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; three-piece bogie; wear; RCF; prediction; traction; braking; heavy haul; simulation; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Maintenance cost is one of the important issues in railway heavy haul operations. For the iron-ore company LKAB, these costs are mainly associated with the reprofiling and changing of the wheels of the locomotives and wagons. The main reason for the wheel damages is usually surface initiated rolling contact fatigue (RCF) on the wheels. LÄS MER

  7. 5. Maintenance performance indicators (MPIs) for railway infrastructure : identification and analysis for improvement

    Författare :Thomas Åhrén; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : With increasing awareness that maintenance not only ensures safety and track performance, but also creates additional value in the business process; many infrastructure managers and owners are treating maintenance as an integral part of the business process. This is also true for the Banverket (Swedish National Rail Administration). LÄS MER
