T., Registration Date 27-12-2002 Organization The Institute of Hydromechanics of the National Academy of Sciences of Ukraine popup.description2 Are developed physical and mathematical model of a linear grating formed by piezoelectric shells raised by an electric signal, and physical and mathematical model of a grating of discrete elements formed by thin piezoelectric plates on which the flat sound wave falls. The appropriate boundary problems(tasks) are solved and effective numerical algorithms for an estimation of acoustic properties of examined systems are developed. On the basis of the numerical analysis a number of laws of interaction piezoelectric systems with a liquid environmental them is established.
