Ploskonos N. Improvement of transversal piezoelectric transformers of linear and oscillation accelerations

3.A research object are processes of transformation of mechanical sizes in electric in the piezoelectric transformers of linear and oscillation accelerations. The aim of work consists in perfection of piezoelectric transformers of linear and oscillation accelerations. For the achievement of the put aim it is necessary to execute next tasks: to analyse the technical level of modern piezoelectric transformers of linear and oscillation accelerations; to build and investigate a mathematical model transversal ring piezoelectric accelerations; to build and investigate a computer model transversal ring piezoelectric accelerations; to work out and experimentally investigate transversal circular transformers of linear and oscillation accelerations; to work out and experimentally investigate transversal domain-dissipative transformers of linear and oscillation accelerations. The practical value of the got results consists in the following: the scientific and technical base of planning of piezoelectric transformers of linear and oscillation accelerations is extended; mathematical and computer models that allow to estimate and forecast working descriptions of circular piezoelectric transformers of linear and oscillation accelerations are built; a transversal circular piezoelectric accelerometer is worked out with a high basic sensitiveness and practically zero lateral sensitiveness; a transversal domain-dissipative accelerometer is worked out with HDR of frequencies(in 2-3 times), and also megascopic sensitiveness(in 1,5-2 times); the results of researches drawn on in industry, in particular, in SIC " Photopribor"(Cherkasies) and OJSK " UkrPiezo", and also in an educational process on discipline the "Transforming devices of devices" in the Cherkasy state technological university. Scientific novelty of the got results : a theory and methods of piezoelectric accelerometer planning got further development, that allows to develop accelerometers with the improved technical descriptions; the method of transversal circular accelerometer form variation that allows to find optimal geometrical parameters at planning of accelerations is first worked out; the mathematical model of transversal circular accelerometer, that allows to promote exactness of linear and oscillation transformers planning, is built and investigational; the method of transversal accelerometer pickoff including is first worked out in differentiative and integrating chains, what a worker allows to extend range of frequencies of accelerometer. The results of researches drawn on in industry, in particular, in SIC " Photopribor"(Cherkasies) and OJSK " UkrPiezo", and also in an educational process on discipline the "Transforming devices of devices" in the Cherkasy state technological university.
