Fault feature extraction of planet gear tooth crack.

What is it about?

The multipoint optimal minimum entropy deconvolution adjusted (MOMEDA) is employed in this paper to extract the vibration feature related to an individual planet gear with tooth-crack fault in a planetary gearbox.

Why is it important?

Weak gear fault related vibration feature is often buried by the strong background noise in the planetary gearbox. It is a challenges for the weak gear fault feature extraction of planetary gearboxes.
