COMPARISON OF VIBRATION ANALYSIS TECHNIQUES FOR RAILROAD ROLLER BEARING DIAGNOSTICS

This paper summarizes investigation of roller bearing defect diagnosis utilizing high frequency vibration techniques. Two devices are reported, one for use at trackside or in wheel shops and the other for initial certification at manufacturing facilities. The first system must be rugged and simple, the second has the qualities of a laboratory device. It is concluded that high frequency peak amplitude detection is a method of weeding out bearings that should be removed from or never enter service.
