침탄치차의 AE법에 의한 크랙발생의 계측에 관한 연구
A Study on Crack Initiation Measurement of Carburized Gear Tooth by Acoustic Emission
초록
Acoustic emission technique is applied to the fatigue crack initiation in a carburized gear tooth. Acoustic emission test performed on carburized gear and three-point bending test equal to carburized gear hardness. The marked acoustic emission are detected at the early stage of crack initiation measured by a crack gauge and the final stage just before the tooth failure. The estimated acoustic emission energy rate are characteristic of the measured acoustic emission.
