Measuring method of unbalance correction amount of elastic rotor and measuring method of influence coefficient used for the measurement

摘要

The method involves stimulating the rotor with a force transverse to the axial direction in each balancing plane, measuring the force spectrum detected as induced vibration characteristics of the rotor and deriving compensation imbalances. The method involves stimulating the rotor (10) with an impact force transverse to the axial direction in each balancing plane (WE1-WE3). The force spectrum of the stimulating force is detected as the induced vibration characteristics of the rotor as a response spectrum in the form of a force or vibration spectrum,. Influencing coefficients are derived., Force or vibration signals associated with rotor revolutions are measured, preferably in the balancing planes. The compensation imbalances are derived from the influencing coefficients and measured force or vibration signals.
