1. 11. 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/Mekatronik

   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. 12. 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

4. 13. Tillståndsövervakning av industriella mekaniska maskiner

   Kandidat-uppsats, Lunds universitet/Högskoleingenjörsutbildning i datateknik

   Författare :Joel Baranji; Adam Abusagr; [2018]
   Nyckelord :tillståndsövervakning; tillståndsbaserat underhåll; likströmsmotor; servomotor; simotion scout; intelligent underhåll; Technology and Engineering;

   Sammanfattning : This bachelor thesis was conducted on a company that for various reasons has chosen to be anonymous. The company works internationally and specializes in industrial machinery within the food industry. Today, maintenance on the machines are performed based on scheduled periods of time, based on the expected remaining useful life. LÄS MER

5. 14. Zedboard based platform for condition monitoring and control experiments

   Kandidat-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Anders Adrielsson; [2018]
   Nyckelord :Condition Monitoring; Matching Pursuit; Dictionary Learning; Zedboard;

   Sammanfattning : New methods for monitoring the condition of roller element bearings in rotating machinery offer possibilities to reduce repair- and maintenance costs, and reduced use of environmentally harmful lubricants. One such method is sparse representation of vibration signals using matching pursuit with dictionary learning, which so far has been tested on PCs with data from controlled tests. LÄS MER

7. 15. Tillståndsövervakning av rullningslager med hjälp av E-näsa

   Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Drift, underhåll och akustik

   Författare :Pontus Kristiansen; Roman Postnikov; [2018]
   Nyckelord :electronic nose; e-nose; maintenance; condition based maintenance; cbm; condition monitoring; MSDF; PCA; arduino; taguchi; MOS Sensor; oil; hydraulic oil; engine oil; transmission oil; gas sensor; e-näsa; elektronisk näsa; underhåll; tillståndsbaserat underhåll; tillståndsövervakning; MSDF; PCA; arduino; taguchi; MOS-sensor; olja; hydraulolja; motorolja; växellådsolja; gas-sensor;

   Sammanfattning : I dagsläget finns det ingen standardiserad metod för att mäta en enhets tillstånd medhjälp av dofter. Vid tillståndsövervakning av rullningslager är vibrationsmätning denmest dominanta metoden. I samband med vibrationsmätning används i vissa falltemperaturövervakning för att få en bättre insikt på rullningslagrets tillstånd. LÄS MER
