Development of the methodic and model of the vibroacoustical signal processing system for the information-diagnosis complex of rotation systems
The two-level vibration control system of complex rotation systems (aviation engines) is developed at the steady-state and non-steady-state modes of operation. At the first level the vibration control system supports the current control of actual levels of vibration at the harmonics of the rotor rotation. The second level is assigned for analysis of “normal vibration” in order to predict or detect small damages of engine rotary details on the bases of integrated usage of signal processing methods for damages diagnosis. The vibration control method is based.
