    Sammanfattning : Safety is more important than reliability or efficiency in railway, aerospace, oil & gas, and chemical industries. Regulations are very restrictive in sectors where safety is paramount. LÄS MER

  4. 3. Model-based Prognostics for Prediction of Remaining Useful Life

    Författare :Madhav Mishra; Jyoti Kumar Sinha; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Sammanfattning : Prognostics and healthmanagement (PHM) is an engineering discipline that aims to maintain the systembehaviour and function, and assure the mission success, safety andeffectiveness. Health management using a proper condition-based maintenance (CBM)deployment is a worldwide accepted technique and has grown very popular in manyindustries over the past decades. LÄS MER

  5. 4. 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
