The correlation structure of the vibration signal of the decanter bearing assembly was analyzed using the theory and methods of statistics of periodically non-stationary random processes. Indicators for detecting and evaluating the propagation of the defects have been developed. The relationship between the width of the fi ltering bandwidth and the parameters of the amplitude spectrum of the signal variation was investigated. 21 Ref., 3 Tabl., 10 Fig.
Keywords: decanter, vibration, trial period, correlation function, spectral density, band fi ltering, defect development indicator
