Effect of increasing the signal-to-noise ratio on the active vibration control of the journal bearings
Original language description
The objective of active vibration control of plain bearings is to extend their operating speed range. The control is carried out by a proportional controller that controls the position of the bearing bushing according to the deviation of the bearing journal position. The piezo actuators are used for bearing bushing motion. Increasing the signal-to-noise ratio of the journal position measurement is achieved with the use of the bandpass filter of the second order in the feedback loop which is tuned to the instability frequency of the whirl type. The center frequency of the bandpass filter is tuned to the rotor rotational speed. At the end of the paper, the results of experiments showing the extension of the bearing rotational speed range without rotor position instability are presented (C) Proceedings of the 26th International Congress on Sound and Vibration, ICSV 2019.
