무인잠수정의 구조설계 및 해석

Abstract

This paper discusses the structural design and analysis of a 6,000 meter depth capable deep-sea unmanned underwater vehicle (UUV) system. The UUV system has been developing by Korea Research Institute of Ships and Ocean Engineering (KRISO), Korea Ocean Research and Development Institute (KORDI). The UUV system comprises three vehicles - a Remotely Operated Vehicle (ROV), an Autonomous Vehicle (AUV) and a Launcher - which include underwater equipment, manipulators and so on. Dry land weight exceeds 3 tons, hence the necessity of making the frame optimal design weight, while ensuring the space within the frame can be put to optimum use for embedding equipment. The structural design and analysis of the ROV and launcher frame system were carried out using the optimizing process. The cylindrical pressure vessels for the ROV were designed to resist the extreme pressure of 600 bars, based on the finite element analysis. The collapse pressure for the cylindrical pressure vessels was also checked through a theoretical analysis.
