FIELD: engines and pumps.
SUBSTANCE: method for determining the dynamic disbalance of the GTE rotor involves installation of vibration sensors on the engine housing at an angle of 90° to each other, processing of the received vibration signals by means of multilevel filtering, allocation in the received vibrating signal of the working field of the rotor frequencies. Then, the instantaneous position of the amplitude and phase of the rotor oscillations is determined, and synthesized orbits are obtained from the displacement of the rotor-housing system in the planes of the rotor supports sections, and the comparison is made with the rotor reference orbit, and the rotor disbalance is determined.
EFFECT: invention makes it possible to determine the engine assembly disbalance at the operating rotational speeds of the rotors.
