An Adaptive Fault Feature Extraction Method for Aeroengine Intershaft Bearing Based on Casing Vibration

Fault diagnosis of the intershaft bearing of aeroengine is quite challenging because vibrations can only be measured on the distant external casing, resulting in weak fault features and complex interference. To address this issue, this paper proposes an adaptive multipoint optimal minimum entropy de...
