摘要
光纤水听器探头是光纤水听器系统的基础。分析了直杆式光纤水听器探头的自由振动特性,用Rayleigh法导出了其基频计算的理论公式,讨论了光纤水听器探头基频的影响因素,并且利用ANSYS对其前几阶固有频率和模态进行了模拟分析,数值结果与解析解比较吻合。
Fiber optic hydrophone unit was the basis of fiber optic hydrophone system. The free vibration characteristics of bar-type fiber optic hydrophone unit were investigated in this paper. By means of Rayleigh＇s method its fundamental frequency was derived, the influence of some parameters on which was analyzed comprehensively. In addition, ANSYS was employed to simulate the natural frequencies and modes of the fiber optic hydrophone unit, numerical results were found to agree well with analytical results.
