함정은 일반 선박과 달리 전투상황을 고려하여 설계 및 건조되어야 하며, 이는 선체뿐만 아니라 내/외부에 설치되는 기자재에 대해서도 동일하게 적용된다. 비접촉 수중폭발에 의해 선체에 전달된 충격파를 감쇠하거나 스스로 견딜 수 있도록 기자재 및 지지부를 설계하고 시험하는 방법이 미국, 유럽 등의 연구기관을 중심으로 연구되어 왔다. 본 논문에서는 함정에 설치된 기자재에 대한 내충격 성능을 평가하는 다양한 설계 기준들에 대하여 소개하고 각 기준들의 적용 방법과 한계 등 특징들을 비교하였으며, 내충격 성능 평가에서 CAE의 필요성과 활용상의 이점들을 기술하고자 하였다.


Unlike ordinary vessels, naval vessel should be designed and built considering the combat situation, and this applies equally to the equipment installed inside and outside the vessels. A method of designing and testing equipments to dampen shock waves transmitted to a ship or to withstand them by a noncontact underwater explosion has been studied by research institutes in the US and Europe. In this paper, various design criteria to evaluate the shock resistance of the equipment installed in the ship are introduced, and the application methods and limitations of each guidance are compared. And finally, the necessity and advantages of the CAE application in the shock resistance evaluation are described.
