Abstract
Способ определения координат источника акустической эмиссии, заключающийся в том, что на контролируемом изделии устанавливают преобразователь акустической эмиссии, изделие нагружают, принимают сигналы акустической эмиссии, генерируемые дефектом изделия, регистрируют моды волн Лэмба в виде волнового пакета, после представления которого частотно-временной зависимостью на спектрограммах выделяют энергетические максимумы антисимметричных и симметричных мод, по разнице во времени прихода энергетических максимумов на выбранных частотах определяют расстояние между преобразователем и источником акустической эмиссии, отличающийся тем, что на контролируемом изделии на некотором расстоянии друг от друга два преобразователя акустической эмиссии определяют расстояние от источника эмиссии до каждого из преобразователей, а по полученным результатам рассчитывают координаты дефекта изделия.A method for determining the coordinates of an acoustic emission source, namely, that an acoustic emission transducer is installed on a controlled product, the product is loaded, acoustic emission signals generated by a product defect are received, Lamb wave modes are recorded in the form of a wave packet, after which the frequency-time dependence is presented in spectrograms distinguish the energy maxima of the antisymmetric and symmetric modes, by the difference in the time of arrival of the energy maxima at the selected frequencies ah determine the distance between the transducer and the acoustic emission source, characterized in that on the controlled product at a certain distance from each other two acoustic emission transducers determine the distance from the emission source to each of the transducers, and the coordinates of the product defect are calculated from the results obtained.
