中文摘要	提出了一种带空气腔芯轴型光纤水听器的结构模型,并对其声压相移灵敏度的响应特性进行了研究.通过对空气腔芯轴型光纤水听器的基本原理和结构进行分析,得出光纤与弹性筒作用的相互关系;建立了动力学等效模型,得出带空气腔芯轴型光纤水听器声压相移灵敏度表达式以及频率特性的理论模型;利用有限元方法,得到芯轴型光纤水听器的响应模型.根据提出的结构和确定的参量制作出相应的探头,经过试验测试,其3dB带宽约为30kHz,测试结果验证了提出的理论模型与有限元模型的正确性.; A structural model of a air-backed fiber-optic hydrophone is proposed and the response of the pressure phase sensitivity is investigated.The interaction relation between optical fiber and elastic tube is gained by the acoustic analyses of the principle and basic structure of the air-backed mandrel hydrophone.Then the equivalent model of the dynamics,the theoretical model of the pressure phase sensitivity and dynamic response model of the fiber-optic mandrel hydrophone are obtained.Also based on the finite element method(FEM),the response model of the hydrophone is proposed.According to the structure which is proposed,the mandrel fiber-optic hydrophone is produced with determined parameters.The pressure phase sensitivity and the 3dB bandwidth achieve about 30 kHz in the test,so the results validate our theory model and the FEM model.; 国家高技术研究发展计划(海上时移地震油藏监测技术)课题“时移地震关键设备研制”子课题(2003AA602110-1)资助
