通过对圆柱形水听器在低频接收时的静态理论分析，得到了 1－ 3型压电复合材料径向极化 圆柱形水听器的自由场电压接收灵敏度计算公式；分析了不同背衬材料及不同厚度的复合材料对 圆柱形水听器灵敏度的影响；实测了 1－ 3型压电复合材料圆柱形水听器的自由场电压接收灵敏度。 试验值与理论计算值基本吻合。
Through static mechanical analyzing on tubular hydrophone at lower operation frequency, a theoretical model on free－ field voltage receiving sensitivity of radial polarized tubular hydrophone is obtained, the different liner materials and different thickness of piezocomposites affecting the proper－ ties of tubular hydrophone were investigated. Radial polarized tubular hydrophone was fabricated using 1－ 3 piezocomposites and the free－ field voltage receiving sensitivity was tested. The theoretical cal－ culated result is well identical with the experimental result.
