Разработка физических основ емкостного акустического метода дефектоскопии металлов

Abstract

Разработана физическая модель процесса возбуждения с помощью конденсатора длинноволновых продольных и поверхностных акустических волн в металлах. Показано, что модель позволяет проводить расчет выходного сигнала и осуществлять выбор методов и средств для приема данных акустических колебаний при проведении дефектоскопии металлов. Установлена возможность возбуждения и приема длинноволновых акустических колебаний емкостными преобразователями. Разработана схемотехническое решение электронного устройства для реализации оригинального емкостного акустического метода дефектоскопии металлов. A physical model with a capacitor for excitation of long-wave longitudinal and surface acoustic waves in metals has been developed. It is shown that the model allows the calculation of the output signal and choice of methods and means for receiving data from acoustic oscillations during the defectoscopy of metals. The possibility of long-wave excitation and reception of acoustic oscillations of capacitive transducers are defined. Solution of the electronic device for implementing the original capacitive acoustic defectoscopy methods designed.
