FIELD: physics.
SUBSTANCE: invention is related to the field of diagnostics of technical condition of machines and mechanisms and may be used for instance for assessment of technical condition of gearwheel, swinging bearings. In method realisation, cepstrum of vibration is built in frequency area, informative components location pitch is linearised by non-linear transformation of frequency scale, significant components are separated, frequencies of significant defects are identified, which are used to evaluate object condition.
EFFECT: higher validity of object condition diagnostics.
