    Sammanfattning : Switches, which are critical components of the Swedish railway, have a neglected maintenance cost that is three times as high as their current annual maintenance cost. Between 2017 and 2018, switches’ reported faults increased by 38 % and about one-third of them caused delays on the regular railway traffic. LÄS MER

  2. 2. Vibration analysis for predictive maintenance of a rotary pump. : Optimal accelerometer configuration based on vibration analysis for cavitation detection of a bi-winged positive displacement pump.

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Gustav Osswald; [2019]
    Nyckelord :;

    Sammanfattning : Predictive maintenance based on condition monitoring uses sensor and system data to prevent damage, in advance to a failure occurring, allowing for a service to be performed at an optimal position in time. Condition based predictive maintenance estimates time of system failure based on a priori information, which has shown to be much more cost effective than traditional maintenance methods. LÄS MER

  3. 3. Data Acquisition using Arrowhead Framework for Condition Based Maintenance of Industrial Equipment

    Sammanfattning : As Industry 4.0 and Internet of Things are established across factories and enterprises, the interest for learning more about these concepts and the possibilities they provide for condition based maintenance is expressed by a factory in Sweden. By addressing the aspects of Internet of Things and Industry 4. LÄS MER

  5. 5. Machine learning for condition monitoring in hydropower plants using a neural network

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Nyckelord :Machine learning; hydropower; condition monitoring; neural network; Kaplan; turbine; feedforwardnet;

    Sammanfattning : The hydro power industry stands for new challenges due to a more fluctuating production fromwind and solar power. This requires more regulation of the production in the hydro powerstations, which increases maintenance demands. An oil leakage has not only consequencessuch as downtimes and maintenance costs, but also an environmental impact. LÄS MER
