| 摘 要： | 文章介绍一种研制成功的自由溢流式质量负载压电圆环阵，该圆环阵由数个短圆环同轴布阵而成。圆环阵的基元(短圆环)是一种开口的切向极化短圆环，短圆环由质量件和压电组件嵌拼而成，这种结构可以有效降低圆环的径向谐振频率；通过调节圆环阵的径长比，可以获得合适的液腔谐振频率，从而有效降低圆环阵的下限频率，拓宽圆环阵的工作带宽，减小发送电压响应起伏。该圆环阵具有低频、宽带、高发送电压响应和大工作深度等优点。

| Abstract: | The paper introduces a free-flooding piezoeletric ring array. The array element is a ring with exposed ends, which is tangentially polarized. The ring is composed of a mass element and a piezoeletric element. By adjusting the ratio between the array's diameter and length, the optimal cavitation frequency can be obtained. As a result, one can expand the frequency band and reduce undulation of the transmission response. The ring array has the advantages of low frequency, wide band, high transmission response and a large working depth. |
