Investigation of characteristics of composite rod-like transducer with arbitrary location of piezoelectric element

Acoustic bulletin, Vol. 3 1, (2000) p.42-50
A dependence of electrical and mechanical characteristics of rod-like composite piezoelectrical transducer on position of piezoactive element of constant thickness is investigated. The problem is formulated in the frame of rod theory and is solved numerically by the method of discrete orthogonolization. Four versions of transducer are considered, which are distinguished by materials of the back and output sections. Comparative analysis of mentioned transducers with respect to various criterions is carried out and practical recommendations on application are outlined.
