Head Yavorskyi Ihor M., Доктор фізико-математичних наук Registration Date 14-03-2025 Organization Physico-Mechanical Institute named after GV Karpenko of the National Academy of Sciences of Ukraine popup.description1 The purpose of the research work is to study the properties of the Hilbert transform of the bi-periodically non-stationary vibration signals, development on this basis methods for separating of the interacting stochastic rhythms and extracting of quadratures of carrier harmonics with combination frequencies, to analyze their auto- and cross-covariation and spectral structures, to study their dependence on damage parameters, to verify the obtained results using simulation models and field data, and to use the developed approach during performing diagnostic work at factories in Ukraine. popup.nrat_date 2025-03-14 Close
