  1. 1. Gearbox fault detection, based on Machine Learning of multiple sensors

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

    Författare :Armands Krumins; [2021]
    Nyckelord :condition monitoring; gear; machine learning; surface fatigue;

    Sammanfattning : The increasing demand for higher efficiency and lower environmental impact of transmissions, used in automotive and wind energy industries has created a need for more advanced technical solutions to fulfil those requirements. Condition monitoring plays an important role in the transmission life cycle, saving resources and time. LÄS MER

  3. 2. Sensors for intelligent and reliable components

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

    Författare :Pontus Lundman; [2020]
    Nyckelord :Wind turbine; Gearbox; Sensor; Condition monitoring; Cyber-physical system; Vindkraftverk; Växellåda; Sensor; Tillståndsövervakning; Cyberfysiskt system;

    Sammanfattning : One way to tackle the climate change society is facing today is through the change to renewable energy sources, such as wind power. Today, a trend when it comes to technology is that products are evolving into becoming more cyber-physical systems (CPS) by integrating functions realized with mechanics, control and communication.

  4. 3. Fault detection of planetary gearboxes in BLDC-motors using vibration and acoustic noise analysis

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Henrik Ahnesjö; [2020]
    Nyckelord :Planetary gearbox; Fault detection; Condition Monitoring; Support Vector Machine SVM ; Machine Learning; Supervised Machine Learning; Defect Pinion; Defect Planet Gear; MATLAB; LabVIEW; Soundproof-box; Noise Vibration Harshness NVH ; Gearmesh Frequency GMF ; Power Spectrum; BLDC-motor;

    Sammanfattning : This thesis aims to use vibration and acoustic noise analysis to help a production line of a certain motor type to ensure good quality. Noise from the gearbox is sometimes present and the way it is detected is with a human listening to it. This type of error detection is subjective, and it is possible for human error to be present.

  5. 4. Tillståndsbaserat underhåll av spårväxlar genom statistisk processtyrning : En fallstudie enligt DMAIC

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Författare :Caroline Hägglund; Oscar Jonsson; [2019]
    Nyckelord :condition-based maintenance; maintenance; DMAIC; point; switches and crossings; statistical proces control; SPC; switches; railway; DMAIC; järnväg; spårväxel; statistisk processtyrning; SPS; tillståndsbaserat underhåll; underhåll;

    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

  7. 5. Bearing Diagnosis Using Fault Signal Enhancing Teqniques and Data-driven Classification

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Benjamin Lembke; [2019]
    Nyckelord :Bearing diagnosis; rolling element bearings; predictive maintenance; signal processing; fault detection; gearbox diagnosis; support vector machine; svm; binary classification; one class classification; machine learning; feldetektion; diagnos; feldiagnos; växellåda; signalbehandling; maskininlärning;

    Sammanfattning : Rolling element bearings are a vital part in many rotating machinery, including vehicles. A defective bearing can be a symptom of other problems in the machinery and is due to a high failure rate. Early detection of bearing defects can therefore help to prevent malfunction which ultimately could lead to a total collapse. LÄS MER
