Abstract

Bimorph piezoceramic elements, in which elastic oscillations of transverse bending are excited, are used to solve a wide range of scientific and technical problems. The relevance of the use of various functional elements of piezoelectronics in power and informational systems is explained, first of all, by their high reliability, as well as small dimensions and weight, which greatly facilitates the solution of the problem of miniaturization of such systems. The technologies and devices that use the direct and / or reverse piezoelectric effect in the principles of their work are promising. The purpose of this article is to study the characteristics of a bimorph piezoelectric element. The main result of this article can be fixed as follows: the paper considers the technology of additional elements, which does not require any refinement of the piezoelement, and the change in the characteristics of the transducer is carried out due to the external circuits for the piezoelement. The influence of additional inductance and capacitance on the amplitude-frequency characteristics of the piezoelectric transducer is studied. The influence of additional resistance connected to piezoelectric transducer’s input on its amplitude-frequency characteristics is investigated. Manipulating the additional elements, you can have a significant effect on the energy of oscillatory motion of material particles of piezoelectric disk volume. The construction and mathematical model of a bimorph disk piezoelectric transformer with a symmetric electric load in a secondary electric circuit, constructed with a minimal number of assumptions, which simplify the real situation, are considered. In addition, using a mathematical model, the sensitivity of the characteristics of piezoelectric transformer to variations in the parameters of its design elements is easily determined. Having these dependencies, it is possible to make a rational choice of the technology for manufacturing a product. Thus, a qualitative mathematical model can significantly reduce the time and cost of developing new models of piezoelectric transformers.
