    Sammanfattning : Early failure detection has been an integral part of condition monitoring of critical systems, such as wind turbines and helicopter rotor drivetrains. An unexplored application of early failure detection is fatigue testing of driveline components. LÄS MER

  7. 5. 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.
