METHOD FOR DETERMINATION OF MAIN TORQUE OF ROTOR UNBALANCE

摘要

Method for determination of main torque of rotor unbalance includes installation of those on pendulum frame, measurement of frequencies of free vibrations in four positions obtained at turn of rotor round its axis each time by ninety degrees and mathematical calculation. Before mathematical calculation one determines main vector of unbalances, its angle and distance between the point with same separation from planes of correction and point of intersection of axis of the article with axis of vibrations of pendulum frame and main torque of unbalances and its angle are calculated by formulae.
