ABSTRACT:
The present invention is a torsional vibration monitoring method and an apparatus for performing the same, in which torsional vibrations produced in a rotating shaft system for use in such as a turbine generator are measured at a small number of certain positions therealong at which the measurements are possible, the torsional vibrations are linearly decomposed and torsional vibrations at arbitrary positions on the rotating shaft system are estimated from the linear decompositions.
