Abstract


Ocean has enormous economic potential and an important strategic position , so countries have developed a variety of instruments and equipment suitable for the detection of deep-sea resources vector hydrophone is one of them . This article describes two structures can vector hydrophone 1000m deep water work : one is the conventional vector hydrophone into the metal pressure shell after the injection of silicone oil obtained deepwater vector hydrophone ; another polymer composite the potting material design made ??air cavity and oil-filled chamber of two Triassic piece deepwater vector hydrophone . Further papers for the preparation process of the polymer potting material research, on the compressive strength of the sample of the material produced in the different preparation process tested , obtained from the material 's Young's modulus for the second water listen simulation study provides basic data . At the same time , the use of ANSYS software simulation study of the pressure hull structure and Triassic piece of hydrophone structure , for two hydrophones structure optimization design reference . The paper design three deepwater vector hydrophone : first just the the conventional vector hydrophone external added a brass shell with a pressure-resistant structure , the theoretical work of the hydrophone depth 1050m, pressure 10MPa after the point it is still good ; except Triassic piece produced by the air cavity vector hydrophone , theoretical work, the depth of 1870m , to directional pressure 10MPa band , normal sensitivity index ; third just oil-filled cavity Triassic piece vector hydrophone theoretical work a depth of 4950m, the band directional pressure 10MPa , the sensitivity indicators still normal . The test results show that : the thesis of three deepwater vector hydrophone are able to work in the 1000m deep water , but more complex production process with pressure hull oil-filled structure deepwater hydrophone sensitivity curve undulating two air chamber deep-water and oil-filled cavity design made ??of polymer materials withstand voltage vector hydrophone better performance , especially oil-filled cavity hydrophone pressure of 10MPa after the acoustic performance indicators of normal , as future design of high-voltage vector hydrophone provides a reference .
