초록

본 논문에서는 예인형 간섭합성개구소나 시스템을 이용하여 실시간 높이 정보를 전시하기 위해 기존의 방법인 synthetic aperture sonar 데이터를 활용하여 높이 정보를 산출하지 아니하고 side scan sonar 데이터를 활용하여 높이 정보를 산출하였다. 초기 모델방법에 비해 해상도는 떨어지지만 처리시간에 있어 상당히 단축되기 때문에 시뮬레이션을 통하여 해상도 및 데이터 처리시간을 비교한 후 실제 시스템에 적용하여 결과를 평가하였다.

Abstract

This study evaluated structural safety of ammunition elevator door for naval vessel by computational aided engineering. First, an initial model that satisfies classification regulations was performed static structural analysis under the hydrostatic loads. As an analysis result, structural vulnerability of an initial model was identified, so a stiffener's volume was selected as an design variables and progressed design reinforcement. The stiffener was reselected based on material cost and strength, and evaluated structural safety of a design reinforced model.
