Емкостные датчики для длинноволнового акустического излучения направленными волнами

Abstract

Рассматриваются с общих позиций состояние, перспективы и возможности применения емкостного метода неразрушающего контроля. Разработана математическая модель процесса возбуждения акустических волн (продольной и поверхностной) с помощью конденсатора, позволяющая проводить расчет выходного сигнала, для последующего выбора методов и средств приема данных акустических колебаний. Разработан макет устройства для реализации емкостного метода. Установлена возможность возбуждения и приема акустических колебаний емкостными преобразователями. Consider from the common position present-day state, prospects and the possibility of non-destructive testing capacitive method using. Developed mathematical model of the process of acoustic wave’s excitation (longitudinal and surface) with a capacitor allow carrying out the output signal calculation for the subsequent choice of methods and devices for receiving the acoustic oscillations data. A device layout has been developed for realization of capacitive method. The possibility of excitation and reception of acoustic vibrations by capacitive transducers it has been established.
