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

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Henrik Ahnesjö; [2020]
   Keywords : 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;

   Abstract : 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.

3. 2. Bearing Diagnosis Using Fault Signal Enhancing Teqniques and Data-driven Classification

   University essay from Linköpings universitet/Fordonssystem

   Author : Benjamin Lembke; [2019]
   Keywords : 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;

   Abstract : 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. READ MORE

4. 3. Robot Condition Monitoring and Production Simulation

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Martin Karlsson; Fredrik Hörnqvist; [2018]
   Keywords : Robot Condition Monitoring Production Simulation SKF ABB IRB 6600 Vibration;

   Abstract : The automated industry is in a growing phase and the human tasks is increasingly replaced by robots and other automation solutions. The increasing industry entails that the automations must be reliable and condition monitoring plays an important role in achieving that ambition. READ MORE

5. 4. Detecting Abnormal Vibration in a Gearbox Using Time-Frequency Domain

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Elisabeth Ibeh; [2012]
   Keywords : Vibration; Complex Morlet Wavelet Transform; Time Domain Averaging; Time-;

   Abstract : The gearbox of Volvo Construction Equipment vehicles may be considered as a critical mechanical component. Gear failures may cause costly down time while the gearbox is repaired. To improve uptime and reduce service costs, reliable and robust real time condition monitoring and diagnostics of gearboxes based on vibration data may be considered. READ MORE

6. 5. Maintenance management of wind power systems : Cost effect analysis of condition monitoring systems

   University essay from KTH/Elektroteknisk teori och konstruktion

   Author : Julia Nilsson; [2006]
   Keywords : ;

   Abstract : The wind power industry has experienced a large growth the past years. The growth mainly focus on a growing market, better economical conditions for wind power because of political decisions and the development of large wind turbines and offshore farms. A goal is to increase reliability for turbines. READ MORE
