| Abstract: | Acoustic emission (AE) is used for gear fault diagnosis. A lot of experimental studies are available in the literature for fault diagnosis. In this study, a theoretical model to correlate the AE energy, generated by crack propagation in gear tooth, to the parameters allied with crack has been proposed based on linear elastic fracture mechanics. It was concluded that AE amplitude is influenced by stress intensity, the length of crack propagation, the progressive area swept out by the propagating crack, and crack length in the gear tooth. The developed theoretical model is validated with the results of experimental investigation found in literature and satisfactory agreement has been observed. © 2017 Elsevier Ltd |
