Abstract
Изобретение относитс к области неразрушающего контрол . Целью изобретени вл етс повышение точности контрол за счет уменьшени длительности акустического импульса и повышение помехоустойчивости. Выполнение пьезоэлемента 1 и волновода 2 в виде равносторонних многогранных призм с количеством боковых граней, равным 5 или 7, обеспечивает снижение уровн сигнала на частотах контурных мод колебаний, что снижает искажени при измерени х и, следовательно, позвол ет уменьшить длительность акустических импульсов. За счет выбора количества боковых граней пьезоэлемента 1, не равного количеству боковых граней волновода 2, частоты их собственных мод колебаний не совпадают, что повышает помехоустойчивость. 1 з.п. ф-лы, 2 ил.This invention relates to the field of non-destructive testing. The aim of the invention is to improve the control accuracy by reducing the duration of the acoustic pulse and improving the noise immunity. The implementation of the piezoelectric element 1 and waveguide 2 in the form of equilateral multifaceted prisms with the number of side faces equal to 5 or 7, reduces the signal level at the frequencies of the contour vibration modes, which reduces the distortion during measurements and, therefore, reduces the duration of acoustic pulses. Due to the choice of the number of side faces of the piezoelectric element 1, which is not equal to the number of side faces of the waveguide 2, the frequencies of their own modes of oscillations do not coincide, which increases the noise immunity. 1 hp f-ly, 2 ill.
