Processing of Vibrodiagnostics Signals Using Specialized Portable Devices

Use of a probabilistic model of vibration signals in the form of a periodically correlated random process allows new opportunities for diagnosing defects in rotating mechanisms at the early stages of their occurrence. Importance of multichannel simultaneous acquisition of vibration diagnostic signals for their join analysis grounded. General requirements to specialized portable devices for acquisition and preprocessing of the vibration diagnostic signals are considered.
