Self-Organizing Map-Based Fault Dictionary Application Research on Rolling Bearing Faults

Vibration signal resulting from rolling bearing defects presents a rich content of physical information, the appropriate analysis methods of which can lead to the clear identification of the nature of the fault. A novel procedure is presented for construction of fault diagnosis dictionary through self-organization map (SOM). The experiments show that the bearing faults diagnosis dictionary could be effectively applied in the vibration pattern recognition for a roller bearing system.
