Bending Vibration Characteristics of a Novel Piezoelectric Composite Trilaminar Vibrator. [PDF]

Materials (Basel), 2021
In this work, the bending vibration characteristics of the 2-2 piezoelectric composite trilaminar vibrator are studied by the finite element simulation and experiment. The simulation results show that the trilaminar vibrator has lower resonant frequency and larger vibration displacement under the fixed boundary condition compared with that of the free ...
