MODELING AN ACOUSTIC CHANNEL OF AN ANGLE DUAL PROBE OF LONGITUDINAL WAVES FOR A CYLINDRICAL REFLECTOR
(pp. 18-27)

Abstract. On the basis of a model of acoustic channel direct dual probe of longitudinal waves for cylindrical reflector the model of channel for angle dual probe with identical parameters of radiating and reception parts is developed. Definition of a wedge angle and a corner of direction on the point of reflection in plane of the control is carried out by the numerical decision of system from two transcendental equations in view of the angle of turn of the angle dual probe influencing both on position of focus and on amplitude of signal in it. This position of the point of reflection on cylindrical hole which varies on parameters of the angle dual probe and its arrangement also is defined. Examples of calculation of signal angle dual probe for various parameters are given and opportunities of influence on its sensitivity are shown.

Keywords: angle dual probe, longitudinal wave, piezoplate, wedge angle, focal point, angle of a turn, directivity characteristic, probe axis, cylindrical reflector, displacement of a reflection point.
