Abstract

A deep-sea pressure vessel needs to protect the internal electrical equipment from the high external pressure. Thus, the pressure vessel should be designed to be watertight and structurally safe. In this study, a cylindrical-type pressure vessel comprising a hollow cylinder and cover plates at both ends is investigated. For communication between the internal electronic equipment and the external device, holes are bored on the cover plate to install underwater connectors. Considering the type of internal equipment and underwater connector specifications, multiple holes may be required. These holes can affect the structural safety of the pressure vessel cover plate. In this study, the optimum design of the hole arrangement in consideration of the structural safety of the cover plate was performed.

심해저 장비에 사용되는 압력용기는 내장된 전자장비를 대기압 상태로 보호할 수 있도록 설계되어야 한다. 따라서 해수에 노출되지 않도록 수밀성과 심해의 높은 압력을 견딜 수 있는 구조적 안전성을 확보해야 한다. 본 연구의 압력용기는 원통형이며, 중앙부의 원통형 용기와 양 끝단의 평판형 덮개부로 이루어져있다. 일반적으로 압력용기 내부 전자장비와의 통신 및 전력전송을 위해 압력용기 덮개판에 다양한 수중 커넥터를 배치 한다. 그러나 한정된 덮개판 공간에 다수의 홀이 배치되면 응력집중을 유발하여 압력용기 덮개판의 구조적 안전성에 영향을 줄 수 있다. 본 논문에서는 구조적 안전성을 고려한 압력용기 덮개판의 홀 배치 최적화 기법에 대한 연구를 수행하였다.
