| 中文摘要: |
| 对用于水声探测的光纤水听器,加速度相移灵敏度是一个重要的参数。本文采用有限元法对空气背衬芯轴型光纤水听器的加速度相移灵敏度进行了理论分析,并通过实验验证,得到了空气背衬芯轴型光纤水听器加速度相移灵敏度的优化规律,提高芯轴壳体的硬度可有效降低光纤水听器的加速度相移灵敏度,而改变芯轴壳体的厚度对水听器加速度灵敏度影响不大。 |

| The acceleration responsivity is a significant parameter for a fiber-optic hydro- phone used in underwater acoustic detection.In this paper,the axial acceleration respons- ivity of an air-backed mandrel fiber-optic hydrophone is investigated by using the finite ele- ment method(FEM),and compared with some experiment result.Some analysis results are given:Increasing the rigidity of mandrel can decrease the acceleration responsivity of the fiber-optic hydrophone and changing the thickness of mandrel has little affect on the ac- celeration responsivity. |
