FIELD: measurement technology, diagnostics of technical state of mechanisms with rotatory units. SUBSTANCE: in agreement with method signal proportional to vibrations of mechanism is digitized after equal spells of time, digitized sequence is recorded and interpolated, dependence of momentary rotational speed of rotating mechanism on time is approximated. Interpolated vibrosignal is digitized on its basis anew at time moments corresponding to angle of turn of rotatory unit. Characteristics of vibrosignal in frequency and time regions are determined. EFFECT: expanded functional capabilities of method thanks to provision of operation under modes with variable rotational speed. 1 dwg
