Description
Устройство, реализующее способ, содержит пьезоизлучатель 1, генератор 2, подключенный к пьезоизлучателю 1, исследуемое тело 3, в котором возбуждают поверхностно-продольные и объемные продольные волны, пьезоприемник 4 и измеритель 5 временных интервалов, св занный с генератором 2 и пьезоприемником 4.A device implementing the method comprises a piezo emitter 1, a generator 2 connected to the piezo emitter 1, the test body 3 in which surface-longitudinal and bulk longitudinal waves are excited, the piezo receiver 4 and the time interval meter 5 associated with the generator 2 and the piezo receiver 4.
Способ осуществл етс следующим образом.The method is carried out as follows.
Ультразвуковые колебани возбуждают в исследуемом теле 3 пьезоизлучателем 1, на который подаетс ультразвуковой сигнал с генератора 2. Ультразвуковые поверхностно-продольные или объемные продольные волны возбуждаютс в зависимости от положени пьезоизлучател 1 и пьезоприемника 4 относительно исследуемого тела 3. Измерителем 5 временных интервалов поочередно замер ют врем t или tp,. прохождени поверхностно-продольных и объемных волн через исследуемое тело 1 длиной d и наход т отношениеUltrasonic vibrations excite in the test body 3 by a piezoelectric transducer 1, to which an ultrasonic signal is sent from generator 2. Ultrasonic surface-longitudinal or bulk longitudinal waves are excited depending on the position of the piezo-emitter 1 and piezoelectric receiver 4 relative to the body under study 3. The meter measures 5 time intervals to alternately measure time t or tp ,. the passage of surface-longitudinal and body waves through the test body 1 of length d and find the ratio
