Popis:	The harmonic response and modal shapes of axially-symmetrical piezoceramic cylinders (tubes) polarised through the wall thickness have been predicted by finite element methods and determined experimentally. Analysis of ceramic cylinders has concentrated on the effects of the variation of diameter to thickness (d/t) ratios, and change in cylinder length (l). Investigation has taken into account material variance and vibration performance with relation to both ‘hard’ and ‘soft’ type ceramics. Computational finite element modelling (ANSYS) and numerical techniques has allowed for the prediction of the harmonic response and modal shapes, thus enabling the choice of cylinder geometry and performance. Resonant frequencies of piezoceramic cylinders have been determined experimentally by impedance analysis. The changes in resonant frequencies have been determined for a range of d/t and l/d ratios and for a variety cylinder of lengths. Predictions of harmonic response of the piezoceramic cylinders are shown to agr...
