DETECÇÃO DE FALHAS POR MEIO ACÚSTICO UTILIZANDO ALGORITMO DE SELEÇÃO NEGATIVA

Abstract

The System Integrity Monitoring (SHM) assesses the situation of aeronautical, civil or mechanical structures and provides the forecast of it is remaining life, acting in decision making, being able to intervene in critical situations. It has emerged as a viable economic alternative for monitoring structures and preventing failures. Thus, thissystem is defined as a prophylactic measure, reliable and effective against structural failure. This work has as objective the theoretical basis and the detection of failures in tubes by acoustic means, following the norm ISO10534-1 (1996) in the sampling. This method of fault detection using acoustic means requires considerably less training data than is usually used in the literature, with approximately 85% less data.
