ABSTRACT:
A method for determining imbalances in a mechanical system, such as a rotor, by detecting oscillations caused by the imbalances, selecting a useful signal having a particular amplitude and frequency from the detected signal, and filtering the useful signal so as to minimize errors contained in the useful signal, and providing a display which indicates the magnitude and phase displacement of the imbalance.
