Discusses issues related to the comparison of the experimental and theoretical results , that is, of acoustic pulses cylindrical piezoelectric transducers that are in the liquid.Electrical block diagram of the measuring system is the base for conducting such research. When this converter is excited at a resonant frequency.Analyzing the experimental and theoretical results, it should be noted that the formulation of the problem was carried out in an analytical form. Formulation and solution of the problem allow us to find the physical characteristics of the studied transition.Based on a comparison of experimental and theoretical work in the conclusion of the applicability of the results in practice, the proposed mathematical models of cylindrical piezoelectric transducers (thin electroelastic bodies), based on the linear theory of electrodynamics and of the Kirchhoff – Love in the time-dependent problems in calculating hydro acoustic transducers.Experimental studies were carried out for commercially available cylindrical transducer brand TSTBS – 3 is in the liquid, and the considered regimes of pulsed electrical excitation are working for most of sonar systems. Tests have shown that the actual design features of the considered cylindrical transducer little effect on the configuration of the acoustic pulses of radiation in different directions. Applied mathematical models of thin electroelastic bodies are recommended for use in the design practice in the design of sonar technology for various purposes.The study of the transition process is relevant for the decision of problems like these.
