Abstract
Presently researching on sensing characteristics of fiber grating hydrophone which are encapsulated with enhancing sensitivity pot are primarily focused on the theoretical and experimental analysis in static or quasi-static conditions. Using the FEM software of ANSYS,the dynamical sensing characteristics of two kinds of fiber grating hydrophone encapsulated with sensing pot have been studied, that one is encapsulated by adhere the package poly to the metal pot and the other is not. And the analysis results reveal that when the package poly has not been adhere to the metal pot, a gain of 52.7 dB in sensitivity can be achieved, and the strain distributed equably in the poly, at the same time,a flat response curve with fluctuation less than ±ldB of the sensor is presented in the frequency range of 0 Hz to 3 kHz.关键词
