Signal processing in Vibration analysis

Christophe Blouet - Watch Now!

This talk will be followed by a Live Q&A Discussion on Zoom.

In the field of rotating machinery, the vibration are widely used to measure health, detect failing parts, improve efficiency or increase life duration of engines and all rotating parts attached. The talk will go through some techniques used and their goals.

spectral kurtois sounds like a brilliant idea for CbM in motors. Please let me know if you have any good references.

I was a helicopter pilot in the NAVY. One maintenance item that needed to be done was rotor blade tracking. Can / is this technology used for rotor blade tracking?

Hi LĂ©onard,
Yes, blade tracking is also done with this kind of equipment, but more with optical sensors, that is sometimes added for temporary measurement, sometimes permanent.
