Empirical model of acousticemission piezoelectric converter
When realixing acoustic emission (AE) methods in the problems of structure strength evaluation parameters and characteristics of sensor signals play an informative part. The processes of a sensor signal formation are rather complicated, of a random nature and physics of signal appearance of acoustic emission is poorly studied. In this case measuring processes are followed by inevitable noises. On the base of analyses of thin structure of seasor signals of acoustic emission using a physical interpretation a model of such signals has been constructed which is sufficiently adequate for use in the processing algorithms.
