摘要

为了进一步拓宽端面拉伸增敏的分布反馈式(DFB)光纤激光水听器的工作频带,研制了一种外径为13 mm的聚氨酯端面拉伸式增敏结构的DFB光纤激光水听器,建立了其声压灵敏度与聚氨酯材料参数的理论模型,仿真分析了水听器的动态特性与聚氨酯材料参数的关系,并制备了参数经过优化后的双组分聚氨酯材料,制作了水听器原型样品并进行了水声实验研究。实验测得,研制的聚氨酯端面拉伸式增敏结构的DFB光纤激光水听器在10~20000 Hz的宽频带内获得了(-137.60±2) dB的声压灵敏度,表明聚氨酯端面增敏式封装有效地拓宽了水听器的工作频带,很好地满足拖曳线列阵的工程化应用要求。

Abstract

To further expand the working frequency band of the distributed feedback (DFB) fiber laser hydrophone, a 13-mm-diameter encapsulated structure with sensitivity enhanced through polyurethane end surface pulling is presented. The theoretical model of the relationship between acoustic pressure sensitivity and polyurethane material parameters is established. After the relationship between the dynamics performance of hydrophone and polyurethane material parameters is simulated, the parameters of the two-component polyurethane are optimized. Prototypes of the hydrophone are fabricated and tested. The acoustic pressure sensitivity reaches (-137.60±2) dB in the frequency range of 10~20000 Hz, which shows that the working frequency band of the hydrophone is expanded through polyurethane end surface pulling and it can well meet the requirements for the engineering application of towed line arrays.
