摘要: 小型水下移动平台自身体积有限，无法搭载大规模被动接收设备，极大限制了对水下目标的接收能力。本文通过建立弱横向耦合厚度振动水听器有限元模型并优化其电声特性，设计了一种基于厚度接收模式传感单元的拖曳细线阵，阵列直径Φ35.6 mm，阵元数8元，阵元灵敏度 ≥ −202 dB。通过将有限元仿真与水下测试实验进行对比分析，验证了弱横向耦合厚度振动接收模式的有效性。
Abstract: Small underwater mobile platforms are limited by their own volume and cannot carry large-scale passive receiving equipment, which greatly restricts their capability of receiving underwater targets. In this paper, a finite element model of a sensing unit with weakly transversely coupled thickness vibration is established and its electroacoustic characteristics are optimized. On this basis, a towed thin-line array based on thickness-receiving-mode sensing units is designed, with an array diameter of Φ35.6 mm, 8 array elements and an element sensitivity of ≥−202 dB. Through the comparative analysis of finite element simulations and underwater tests, the effectiveness of the weakly transversely coupled thickness vibration receiving mode is verified.
