본 논문에서는 전산해석을 통하여 함정 탄약승강기 수밀문에 대한 구조적 안정성을 평가하였다. 먼저, 선급 규정을 만족하는 초기 모델에 수두압에 따른 하중을 부여하여 정적 구조해석을 수행하였다. 해석 결과, 초기 모델의 구조적 취약성을 확인하였고 보강재의 부피를 설계 변수로 지정하여 설계 보강을 진행했다. 수밀문의 재료 비용, 강도를 고려하여 보강재를 재선정하였고 설계 보강안의 구조적 안정성을 평가하였다.

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.
