Raevskiy N. The methods and devices for the defects diagnostics of bimorph piezoelectric elements

The methods and devices for the defects diagnostics of bimorph piezoelectric elements. The Object is the troubleshooting of bimorph piezoelectric elements. The Objective is the development of new methods and devices for bimorph piezoelectric elements. The methods used in the research are the methods of linear circuit theory, the electromechanical analogy method, elements of automatic control theory. Mathematical and computer simulation models of the troubleshooting devices were developed and researched. The method based on the form of the transfer characteristic is developed. The troubleshooting devices for bimorph piezoelectric cells by means of inductive and piezoelectric transformers and oscillating circuits are developed and implemented. The sphere of device implementation is the production of bimorph piezoelectric elements.
