Proc. ASME. DETC98, Volume 8: 1998 Power Transmission and Gearing Conference, V008T08A016, September 13–16, 1998
Paper No: DETC98/PTG-5794
...Abstract Abstract Vibration and debris monitoring methods are being increasingly used to detect gear tooth breakage. In this paper an alternate method of detecting gear tooth cracking is investigated. It is based on the phenomenon of acoustic emission (AE). The detectability of growing cracks...

Proc. ASME. IDETC-CIE2001, Volume 6B: 18th Biennial Conference on Mechanical Vibration and Noise, 2033-2042, September 9–12, 2001
Paper No: DETC2001/VIB-21541
...Abstract Abstract A distributed in-situ sensor that can simplify structural health monitoring is investigated in this paper. The distributed sensor can detect damage within the coverage area of the sensor by measuring acoustic emissions, but it cannot exactly locate the damage source due...

Proc. ASME. IDETC-CIE2007, Volume 7: 10th International Power Transmission and Gearing Conference, 553-559, September 4–7, 2007
Paper No: DETC2007-34744
... 22 05 2009 This paper presents experimental evidence of the correlation between Acoustic Emission (AE) activity and the specific film thickness (λ) for operational spur and helical gears. Whilst recording AE activity for a range of test conditions the specific film thickness was varied...

Proc. ASME. IDETC-CIE2003, Volume 4: 9th International Power Transmission and Gearing Conference, Parts A and B, 653-656, September 2–6, 2003
Paper No: DETC2003/PTG-48083
... It is widely recognised that Acoustic Emission (AE) is gaining ground as a Non-Destructive Technique (NDT) for health diagnosis on rotating machinery. This paper reports on part of an ongoing experimental investigation on the application of acoustic emission for gear defect diagnosis...

Paper No: DETC2005-85658
... data of a milling process is used in an experimental work to demonstrate the suggested methodology. Fourier Transformation and Wavelet are used for data analysis. The results show that the suggested approach is most suitable for vibration and acoustic emission sensors to improve the reliability...
