Abstract
An Interferometric fiber optic hydrophone is designed in this work with a composite concentric structure. The structure is made of different layers having a variable material and structural properties. The mandrel is designed to withstand a natural frequency ranges from 0.2 to 2.5 kHz. The objective of the work is to design the mandrel which is placed at a distance ranging from 20 to 200 m underwater with varying boundary conditions. Boundary conditions specified are innermost layer of the mandrel is fixed and pressure is applied to the outermost layer of the mandrel. The design is feasible with two optic fiber layers which are wound over the center of the length of the mandrel. Preprocessing of design is made using Hyper Mesh; analysis is performed in ABAQUS 6.10 CAE tool and visualization of results in hyper view. Whenever the pressure is applied to the mandrel, the phase change of light happens which can be to calculate sensitivity mathematically.
