ON THE INFLUENCE OF THE PRISM MATERIAL AND THE PIEZOCERAMIC ON THE SOME CHARACTERISTICS OF A PULSE SIGNAL OF THE ANGLE PROBE OF SHEAR WAVES
(pp. 16-24)

Abstract. On the basis of computer simulation of an echo signal of the angle probe of shear waves from the reflector such as a side drilled hole for a prism of the angle probe from different materials (organic glass, polystyrene, caprolon and polycarbonate) and several types of piezoceramic piezoelectric element (ZTP-19, PZT-5H, ZTP-19М) is rotined, that for frequency of the probe 2,5 MHz the greatest amplitude of an echo signal was reached for a prism of the angle probe manufactured of organic glass. The same outcome was watched for frequency of the converter 5 MHz and piezoceramic such as ZTP-19. On width of a frequency spectrum of an echo signal the material of a prism, despite of different damping of a longitudinal wave in it, influences unsignificantly. For a prism of the converter from polystyrene, caprolon and polycarbonate of amplitude of echo signals for the same reflector (side drilled hole) accordingly on 2,3, 4,2 and 14,5 dB it is less, than amplitude for a prism from organic glass. According to the parameters of the echo signal, it is possible to evaluate the optimal choice of the prism material of a angle probe, taking into account its features and characteristics of piezoceramics. Calculations allow us to determine the frequency limits of the use of various prism materials.

Keywords: angle probe, shear wave, longitudinal wave, prism, organic glass, polystyrene, echo signal, frequency spectrum, pulse, angle of probe, side drilled hole, type of piezoelectric ceramic.
