Analysis of vibration signal of bearing unit with developed defect based on methods of statistics of periodically correlated random processes

I. Y. Matsko

 
Vibrations of bearing unit decanter with developed defect based on their mathematical model in form of periodically correlated random process were analyzed. Considered were the properties of deterministic as well as periodically nonstationary stochastic constituents. The peculiarities of spectrum-correlation structure of the latter, which characterize defect of this type and can be used for its early detection, were determined. Ref.10, Figures 13, Tables 2.
 
Keywords: bearing unit, vibration, periodically correlated random process, developed defect, typical defect characteristics
