Vibroacoustic System VAS-1 for Early Vibration Diagnostics of Rotating Mechanisms

Section: Scientific Basis of Innovation Activity
Language: Ukrainian
Abstract: Vibroacoustical system developed in G.V. Karpenko Physicomechanical institute of NAS of Ukraine and intended for detection and diagnostic of rotating mechanisms defects on their early stage is presented. It is based on theory and statistic methods of periodically non-stationary random processes and their generalizations. The functional properties of the system are described. The example of its usage for detection and identification of sliding bearings defects of turbo-unit of power plants is shown.
Key words: vibroacoustic system, defects in the mechanisms, periodically nonstationary random processes.
