Abstract

This paper introduces the concept of the computer-aided engineering(CAE) design method for a bypass valve in a system that is used for the safe lifting of mineral resources in deep-seabed mining. Although the bypass valve has a simple mechanism, its design is very difficult because of various influencing factors. This equipment, which has a complex design process, should be developed by CAE-based design method. The method can perform the design, design verification, and virtual experiment at the same time. In this study, the CAE-based method for the design of the bypass valve has been developed using fluid dynamics, multi-body dynamics, and optimization method.

본 논문은 심해저 채광시스템 중 심해저 광물자원의 안전한 양광을 위한 바이패스 밸브의 개념 소개 및 CAE 기반의 바이패스 밸브 요소 설계 기술을 고찰하고 있다. 바이패스 밸브는 다른 해양의 기자재와 같이 고장예방과 안정성 확보를 위해 간단한 구조로 제안되었으나, 유체, 구조, 동적 거동 등의 다양한 영향으로 인해 설계는 복잡하고 어렵다. 설계가 복잡한 바이패스 밸브를 개발하기 위해서 본 연구에서는 CAE 기반 설계 기술을 활용하였다. CAE 기반 설계 기술은 설계, 설계검증, 가상의 실험 등을 한 번에 할 수 있어 바이패스 밸브와 같이 복잡한 설계 문제 해결에 효과적이다. 특히, 바이패스 밸브에 사용되는 스프링은 밸브 특성에서 가장 중요한 응답 성능에 관련된 부품으로 유체력, 동역학을 이용한 CAE 기반 설계 기술을 적용하는 것이 효율적이며, 이를 위해 각 학제들을 연동한 통합설계 모델을 개발하였다. 이러한 통합설계 모델을 바탕으로 바이패스 밸브의 설계 및 설계에 대한 검증을 수행하였으며, 이러한 일련의 과정을 통하여 바이패스 밸브를 개발하였다.
