Some problems of the differentiated vibration measurement of rotors systems

The paper investigates the means of differentiated vibration measurement of rotor systems of various assignments, which does not depend on sensor displacement (vibration of sensors). It is demonstrated that the presented method of vibration measurement allows differentiating in measurement process the cause of vibration such as mass eccentricity, non-round form of rotor, etc. Furthermore, it also excludes influence of change of sensor position with respect to supervised rotor and/or immovable coordinate system (sensor vibration) onto results of measurement of vibration parameters.
