Identification of Dynamic Bearing Parameters: A Review

摘要: In this paper, we present a review of the experimental identification dynamic parameters bearings in rotating machine. Major emphasis is given to vibration-based methods and encompasses descriptions measurement techniques, mathematical modeling, parameter extraction algorithms uncertainty estimates applied variety bearings. The include governing equations rotor-bearing system both time frequency domains. techniques have been classified based on used excite system. includes similar components, which play an active link between stationary parts Based state art bearing identification, conclusions are made future directions suggested.
