摘要：
The shear vibration modes (d15 mode) of piezoelectric ceramics have many advantages, such as high electromechanical coupling coefficient, generally higher piezoelectric constant, low frequency constant, and dielectric constant. It thus has a good performance in piezoelectric energy collector and new structural composite transducers. The shear vibrations generated by the piezoelectric ceramics were converted into the thickness vibration of the composite with designing a transition layer with a special structure. At the same time, this transition layer meets the requirements to radiate underwater longitudinal wave, and thus improves the piezoelectric properties of composite materials. The impact of the transition layer material types on the overall performance of the composite material was studied through the finite element analysis and experiments. © 2019, Editorial Office of Journal of Vibration and Shock.
