METHOD OF DETERMINATION OF VALUE AND ANGLE OF DISBALANCE Russian patent published in 1997 - IPC

FIELD: measurement technology, determination of disbalance of rotating mechanisms of cyclic action. SUBSTANCE: during processing of vibrosignal of rotating part rotation period is divided into n phase values relative to initial phase of cycle, cophased values of vibrosignal are summed for m periods and periodic component of vibrosignal is extracted as functional of angle of turn of rotating part relative to initial phase. Then Fourier transform of extracted periodic component is carried out, amplitude and phase of first harmonic are determined and used to evaluate value and angle of disbalance. EFFECT: enhanced efficiency of method.
