REPORT NUMBER: DOT/FRA/ORD-00/06.I
KEYWORDS: Acoustic Detection of Railcar Roller Bearing Defects; acoustics; roller bearing defects; raceway spalls; water etching; loose bearing components; spun cones
ABSTRACT: A series of tests were performed at the Bearing Test Facility at the Transportation Technology Center,Inc. (TICI) in Pueblo,Colorado, to gather acoustic and acceleration emissions for a number of roller bearing defect types designated by the rail industry as a priority. This database will be used to develop data processing techniques for the recognition of these defect types via wayside sensor systems.
