Spur gear tooth root crack detection using time synchronous averaging under fluctuating speed

a b s t r a c t Filtering techniques are used to improve the signal to noise ratio (SNR) for better feature extraction. The time synchronous averaging (TSA) is one of such method that is based on averaging periodic sections. However, it fails to give significant results for an asynchronous or fluctuating speed condition. […]
