Abstract
The paper describes the properties of a model of vibration of interconnected rotating mechanisms in the form of biperiodically nonstationary random processes (BPNRP). Individual cases of such a model are considered, which enable performing data analysis by the method of periodically nonstationary random processes (PNRP). These methods are used to analyze the condition of mechanisms at increased vibration level. Separation of deterministic and stochastic vibrations was performed and parameters describing the structure of hidden periodicities of the first and second order were determined. The causes for increased vibration level were established.
Keywords: lifting mechanism, vibration, periodical nonstationarity, deterministic oscillations, amplitude spectrum, stochastic high-frequency modulation, dispersion
