Each of these vibration sources produces vibration at a particular factor times the rotational speed of the machine. Rotating machinery can generate rotational speed-dependent vibration at natural structure resonance and natural frequencies. These often cause high vibration levels and vibrational problems - even a disaster could strike.
Vibration data - so get some sensors acquiring data! Summary metrics - vibration signals are complex, so quantify it into a handful of metrics; Monitor those metrics - changes in these metrics will indicate change in the system; I went through 12 different vibration metrics, but if I had to pick my top 3 they would be: RMS acceleration; RMS ...
