Selection of the level of vibration signal decomposition and mother wavelets to determine the level of failure severity in spur gearboxes

open access: yesQuality and Reliability Engineering International, Volume 40, Issue 6, Page 3439-3451, October 2024.
Abstract Spur gearboxes are an integral component in the operation of rotary machines. Hence, the early determination of the severity level of a failure is crucial. This manuscript delineates a methodology for selecting essential mother wavelets and filters from the wavelet transform (WT) to process the vibration signal within the time‐frequency domain,
