  1. 1. Ramverk för en drift- och underhållsstrategi ur ett regelstyrt infrastrukturperspektiv

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

    Sammanfattning : Managing the Swedish state railways is a complex task where internal and external factors must be taken into consideration at the same time as demands for efficiency are made by owners, customers and end customers. Banverket (‘The National Swedish Rail Administration') was formed in 1988 by the Swedish State Railways, a public service corporation, being divided into an infrastructure unit, Banverket, and a transport enterprise, SJ (‘the Swedish State Railways').

  3. 2. Analys av statistik om spårväxlars underhållsbehov

    Författare :Arne Nissen; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Banverket har behov att det genomförs analyser till orsaker till funktionstörningar och förseningstid vid infrastrukturen. Spårväxlar är en av de anläggningar som har många funktionstörningar. Syftet med studien har varit att ta fram ett arbetssätt för att värdera enskilda spårväxlars funktionssäkerhet. LÄS MER

  4. 3. Maintenance strategy for a railway infrastructure in a regulated environment

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

    Sammanfattning : The operation and maintenance of railway infrastructure is complex, strictly regulated by government legislation, and must be working in close cooperation with all the stakeholders including customers involved, in order to avoid sub optimization. The business configuration of the Swedish Railway system makes it very difficult to optimize the entire railway operation, as many times its stakeholders have conflicting demands. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; vacuum technology; hydraulics; Mechanical engineering; a cost-effective vibration-based maintenance policy.; Integrated maintenance; Condition monitoring and control; Total Time on Test-plots; Vibration monitoring; effectiveness and accuracy; Failure causes and mechanisms; Maintenance quality; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; Commercial and industrial economics; Industriell ekonomi; Maintenance Technology; Terotechnology;

    Sammanfattning : Modern machinery is expensive and therefore must run at high availability and effectiveness which cannot be achieved without an effective maintenance policy. Condition monitoring, (CM), techniques can be utilised to reduce or arrest the rate of deterioration of a component so increasing operating life. LÄS MER
