Yv. Lange et al., SPECTRA OF PULSED SIGNALS OF TRANSDUCERS OF LOW-FREQUENCY ACOUSTIC FLAW DETECTORS, Russian journal of nondestructive testing, 32(5), 1996, pp. 337-347
Spectra of pulsed signals of piezoelectric and impact transducers of l
ow-frequency acoustic flaw detectors are examined. The effect of the i
mpedance of mechanical loading of combined and separate-combined piezo
electric transducers on their natural frequencies and their spectra of
output signals is analyzed. The effect of the parameters of impact tr
ansducers on the spectra of acoustic pulses excited hy them is investi
gated.
