摘　　要：该文仿真设计了一种高频压电复合材料球形换能器,利用COMSOL软件建立了有限元模型,计算了换能器的声辐射特性,分析了不同压电陶瓷材料、不同基元尺寸对换能器声辐射特性的影响。仿真分析结果表明,球形高频换能器具有高频、宽带及可全向辐射声波等特性,能广泛应用于水声探测与成像发射换能器及其阵列。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.
