VIBROACOUSTIC SPECTROMETRY SYSTEM FOR THE NON-DESTRUCTIVE ANALYSIS OF MATERIALS (MACHINE-TRANSLATION BY GOOGLE TRANSLATE, NOT LEGALLY BINDING)

Spectral system by indirect impact vibroacoustic waves for the analysis of mechanical, chemical and material defects. The use of a structure consisting of an antivibration platform, a resonant plate, a hammer and microphones in the audible range connected to a system of acquisition, processing and data analysis is detailed and claimed. Its application focuses on the characterization of materials, both in solid and fluid phases, by determining their elastodynamic properties, as well as alterations in their chemical or structural composition, using spectroacoustic techniques in the audible frequency range.
