    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Sammanfattning : The railway is an important mode of transport, due to its environmental friendliness, high safety level, and low energy consumption, among other reasons. Railways provide a sustainable means of transporting a large amount of freight and passengers, in a cost-effective and comfortable way. LÄS MER

  3. 7. Enablement of digital twins for railway overhead catenary system

    Författare :Amit Patwardhan; Ramin Karim; Rikard Granström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway catenary; Maintenance; eMaintenance; LiDAR; Point Cloud; Digital Twin; Software Architecture; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Railway has the potential to become one of the most sustainable mediums for passenger and freight transport. This is possible by continuous updates to the asset management regime supporting Prognostics and Health Management (PHM). Railway tracks and catenaries are linear assets, and their length plays a vital role in maintenance. LÄS MER

  4. 8. Measurements and analysis of electromagnetic interferences in the Swedish railway systems

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

    Sammanfattning : Presently, the existing failure reporting system at Banverket (the Swedish Rail Administration), which handles reports on the failures of the railway infrastructures and possible causes of failure, is not optimum (or most suitable) when it comes to analysis of electromagnetic compatibility (EMC)- related failures and causes. This failure reporting system is reliant on correct reporting into the system, so that the right information can be sent back to the users, the maintenance and service personnel, in real time.

  5. 9. Assessment of fatigue resistance and strength in existing concrete structures

    Författare :Håkan Thun; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : During the last few decades, it has become more and more important to assess, maintain and strengthen structures like bridges, dams and buildings. This is mainly due to the fact that: (a) many structures are getting old and many have started to deteriorate, (b) there is sometimes a need to increase the load carrying capacity of an existing structure due to e.
