A multichannel multiplicative method for acoustic testing of large-size compact concrete building constructions
A new multichannel acoustic method for testing large-size concrete building constructions is considered. The method is based on the use of a method of free vibrations (the resonance and impactecho methods) with the subsequent multiplication of partial spectral characteristics. The multichannel multiplicative method allows performance of acoustic testing of large-size compact concrete building constructions (blocks, beams, columns, supports, and other standard articles). The developed algorithms for testing compact BCs, which involve construction of dispersion characteristics and determination of zones for optimal arrangement of transducers, allow adaptation of the proposed method to testing of arbitrarily shaped compact articles. However, in this case, it is necessary to construct an individual dispersion characteristic and identify particular optimal zones for positioning transducers for each new shape of an article. Hence, as a result of studies performed at the Moscow Power Engineering Institute, a multichannel RMM for testing large-size compact concrete articles with unambiguous spectrum interpretation has been developed. This method allows determination of both the thickness of a tested article and the velocity of acoustic vibrations in it.
