摘要

The paper reports the process of discrimination between signatures due to four possible causes in turbo-generator dynamics. These four aspects, rotor dynamics, structural dynamics, electro dynamics and fluid dynamics, have different systematic effects in the time-frequency response of the structure which make it possible to resolve the effects by identifying coupled behaviour between frequency components, transducer types and transducer locations.
