Использование пассивных фильтров в преобразователях акустической эмиссии

Abstract

Object of investigation: passive filter for acoustic emission (AE) sensor. The aim of this work is to improve the accuracy of determining the coordinates for the AE method. A passive filter was developed for the AE transducer, which makes it possible to improve the accuracy of determining the coordinates of the AE source on an extended object. The developed passive filter allows recording AE signals in a given frequency range, increases the sensitivity of the AE transducer in the specified range.
