On the detection of natural frequencies and mode shapes of submerged rotating disk-like structures from the casing
Natural frequencies of a rotating disk submerged have been analyzed from the rotating and from the stationary frame. Disk is excited from the rotating frame with PZT. Measurement from the rotating and from the stationary frame. Transmission from the rotating to the stationary frame is studied. Detection of the natural frequencies and mode-shapes from the stationary frame.
