Abstract
Utilization of synchronous averaging enables to point out which gear shaft of a gear system is the origin of 'ghost noise' that is not integer order of mesh frequency. But when plural gears are on a shaft generating ghost noise, it is difficult to point out which gear is the origin. In this study, we propose detection method of trouble gear utilizing amplitude fluctuation analysis. Proposed method is verified with vibration measurement result of two-stage gear reduction system.
