METHOD FOR VIBRATION DIAGNOSTICS FOR DETECTING INCIPIENT DEFECTS OF INDUSTRIAL EQUIPMENT Russian patent published in 2022 - IPC G01M13/04 

FIELD: diagnostic equipment.

SUBSTANCE: invention relates to vibration diagnostics of industrial equipment and can be applied to vibration diagnostics of working industrial mechanisms (bearings, pumps, gearboxes, electric motors and other rotary mechanisms). The method consists in measuring vibration accelerations and converting them into direct auto power spectra and envelope spectra of the high-frequency component of vibration acceleration signals, highlighting local maxima in them and comparing them with maxima on predefined reference auto power spectra and envelope spectra, the formation of reference auto power spectra and envelope spectra of vibration signals is carried out by determining a set of frequencies corresponding to each defect. At the stage of vibration diagnostics, the presence of a defect is judged by the correspondence of the local maxima and reference sets of frequencies allocated on the spectra, the change in the frequency set, the characteristics of the vibration acceleration spectra and the number of defects is made by additionally introduced external software modules without changing the main software.

EFFECT: obtaining more output data by varying the initial parameters during signal processing.
