摘要

一种新型叠层式压电换能器主要由压电陶瓷、金属螺栓、橡胶垫片、铜电极、防水层和输出电缆组成。利用ANSYS10.0软件分别在空气和水中建立了换能器有限元模型，计算了换能器的谐振频率、电导、发射电压响应和指向性。仿真结果表明，叠层结构有效地提高了压电换能器的灵敏度。该压电换能器的最大发射电压响应可达到155 dB以上，比传统设计提高了约10%。

Finite Element Analyses for Radial Piezoelectric Mode Laminated Transducer

A novel laminated piezoelectric transducer was mainly composed of the piezoelectric ceramics, metal bolt, rubber gasket, copper electrode, waterproof layer and output cable. The transducer finite-element modeling was built, separately in the air and water, with ANSYS10.0 to calculate the resonance frequency, conductance, transmitting voltage response and directivity. The simulation showed that the laminated structure effectively improved the sensitivity of the piezoelectric transducer. The maximum transmitting voltage respond of the laminated piezoelectric transducer can achieve more than 155 dB, compared with a traditional design by approximately 10%.
