ABSTRACT:
The disclosed torsional vibration monitoring method measures torsional vibrations produced in a rotating shaft system, for apparatuses such as a turbine generator, at a small number of measurable points on the system and the measured torsional vibrations are linearly separated to estimate torsional vibrations at arbitrary positions of the system are estimated. According to one high precision torsional vibration monitoring method, up to 2n torsional vibrations at the arbitrary positions are obtained from the torsional vibrations detected at n selected positions of the rotating shaft system.
