摘要： To improve the coupling adjustment workability and precision of a rotor, irrespective of change in bearing characteristics due to an increase of rotational speed, the apparatus detects angular frequencies (.omega.) and reference mark positions (.theta.) of the rotor; detects vibration displacements (r) of the rotor; analyzes vibration vector components (.omega.), (r) and (.theta.) of rotation synchronizing vibrations; extracts a specific angular frequency (.omega..sub.1) at which a higher harmonic vibration frequency (.omega..sub.R) matches a natural frequency of the rotor, and various rotation synchronizing vibration vector components at (.omega..sub.1), at (.omega..sub.R) and (.omega..sub.2 to .omega..sub.i), respectively; estimates static vibration vector components (r.sub.0, .theta..sub.0) at zero angular frequency (.omega..sub.0) on the basis of rotation synchronizing vibration vector components (r.sub.T, .theta..sub.T) at (.omega..sub.1 to .omega..sub.i) and in accordance with a polynomial; obtains dynamic vibration vector components (r.sub.n, .theta..sub.n) by subtracting the static vibration vector components (r.sub.0, .theta..sub.0) from the rotation synchronizing vibration vector components (r.sub.Tn, .theta..sub.Tn), respectively; identifies a vibration response function; and estimates an eccentric direction (.theta.) and an eccentric quantity (.delta.) to be adjusted on the basis of (r.sub.n, .theta..sub.n) at (.omega..sub.R) and at (.omega..sub.1 to .omega..sub.i) and in accordance with the identified vibration response function. Further, the real time vibration status of the rotor and the estimated eccentric direction and quantity are all displayed.
