FEATURES OF THE AE METHOD APPLICATION IN MONITORING THE BRIDGE CONSTRUCTIONS
(pp. 32-39)

Abstract. The experiment results of estimating the efficiency of the Acoustic Emission method application to monitoring the highway bridge constructions are produced in the article. The main difficulties arising during monitoring the similar kind of objects are considered. Extremely high level of the acoustic noise is recorded. All the noises are classified into two types. The specific views of signals in time and frequency domains are presented for each type. Method of noise suppression is offered. This method includes choice of the optimal working frequency band and application of the multilevel discrimination algorithm to the AE parameters. The probability of detection of the acoustic emission sources with various distances between transducers is also estimated.

Keywords: acoustic emission, monitoring, bridge constructions, filtering.
