| Abstract: | In this paper, the high frequency piezoelectric composite spherical transducer is simulated and designed. A finite element model is established by COMSOL software to calculate the acoustic radiation characteristics of the transducer. The influence of different piezoelectric ceramic materials and different primitive sizes on the acoustic radiation characteristics of the transducer is analyzed. The simulation results show that the spherical high-frequency transducer has the characteristics of high frequency, wide band and omnidirectional acoustic radiation, and can be widely used in underwater acoustic detection and imaging emission transducers and their arrays. |
