Is it possible to average out synchronous vibration?
Is it possible to average out synchronous vibration?
(OP)
Dear all,
I am new to the vibration analysis field. I am curious to know, is it possible to average "out" synchronous vibration data by using an analyser?
I know that synchronous time averaging with the help of a tracking filter helps in eliminating noise. Is the reverse possible? Can I use a tracking filter (key phasor or reflective tape laser sensor) to remove the synchronous components from a signal? In a hypothetical scenario where the GMF and any other high frequency vibration i.e. BPFI & harmonics or vane pass frequencies lie close to one another, will removing the synchronous components from the signal be helpful in identifying/emphasizing the non-synchronous bearing fault frequencies?

I have no idea if modern software packages offer that manipulation.

You could also search for Emerson-CSI PeakVue as another related method.
