Focusing Properties

In this paper the characteristics of acoustic field for miniature cylindrical focused transducer with a hole was studied in order to instruct the optimization design of the transducer for both realizing visualization and improving the treatment effect. Then the acoustic field was simulated numerically with different parameters of hole. It is found that position of focus is almost unchanged but acoustic pressure amplitude declines. In addition the performance of transverse focusing for the focal plane and levels length of acoustic pressure are lowered. Moreover, if size of transducer and rigidity of material permit, the area and ratio of width to height for the hole should be reduced appropriately to improve the focusing properties. And it is deduced that area and ratio of width to height for the cylinder can be increased to achieve the same therapeutic effect with a fixed hole size.

Theoretical Results

 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.
