Abstract: The present invention relates to the technique for dynamic balancing of rotating bodies and may be used for measuring and correcting forces generated by unbalance of rotors, in particular, rigid rotors. The claimed method allows measurement of the rotor imbalance parameters with high accuracy in two imbalance datum planes. The method is based on imparting of oscillatory motion to a rotor and to a coaxial balanced body relative to a fixed point selected at the common axis of the rotor. To increase accuracy of the method, simultaneously in each time in the plane passing through the above fixed point, forces opposing angular oscillations of the balanced body relative to an axis are exerted to the balanced body tangentially.
