Observation of Changes in Acoustic Emission and Vibration

Acoustic emission technology is also used to monitor the four-point flexural fatigue crankshaft made of 42CrMo [5]. The specimens divided into two categories, namely, pre-existing cracks and non-existing cracks, which simulates the crankshaft and the new crankshaft. The method parameter
