ANALYSIS ON PERFORMANCE OF FLEXTENSIONAL PIEZOELECTRIC HYDROPHONE

摘要：

　　A theoretical model of flextensional piezoelectric hydrophone (FPH) is proposed to meet the requirements of high sensitivity and low frequency.The FPH is two circular piezoelectric layers with a laminated structure.Two kinds of the connection forms of the two piezoelectric plates, in series and in parallel, have been studied.The effect of geometrical parameters, thickness and radius, on the detection performance has been investigated to improve sensitivity of the FPH around the low frequency range.Moreover, the theoretical results are verified by finite element method.Moreover, the theoretical solutions under geometric optimization are obtained.The results provide a theoretical basis for design of the FPH.
