Effect of Specific Acoustic Resistance of the Matching Layer on the Duration of the Pulse Radiated by a Transducer
Source abstract
Abstract
Based on numerical calculations, changes in the duration of a radiated acoustic pulse due to small deviations in the specific acoustic resistance of the quarter-wave matching layer from the optimum value (from the viewpoint of producing the smallest pulse duration) are studied. We have determined the acceptable range of specific acoustic resistances of the matching layer, in which the duration of a radiated pulse of the particle velocity at the output of a transducer in the form of a piezoelectric plate with a quarter-wave matching layer and different degrees of damping does not increase considerably. These data can be used for rejecting blanks at the early stages of manufacturing transducers.
