Abstract

In order to build protective facilities and structures in the defense field, a prior review of the impact of explosion pressure on the structure is necessary, and the protection performance for expected explosion conditions must be satisfied. Accordingly, the Ministry of Defense’s protection design standards have been established and standards for military facilities have been established, but special facilities such as ground combustion test sites are not presented. Therefore, in this study, the protection performance evaluation process of the ground combustion test site protective structure was established and the protection performance evaluation was performed by performing finite element analysis using LS-DYNA to analyze the interaction of explosion pressure.

Protection Performance Evaluation

국방 분야 방호시설 및 구조물을 구축하기 위해서는 폭발압력이 구조물에 미치는 영향에 대한 사전 검토가 필요하며, 예상되는 폭발 조건에 대한 방호성능을 만족하여야 한다. 이에 따라 국방부는 방호 설계기준을 정립하여 군사시설물에 대한 표준을 정립하였으나, 지상연소시험장과 같은 특수시설물에 대해서는 제시되지 않고 있다. 따라서 본 연구에서는 지상연소시험장 방호구조물의 방호 성능 평가 프로세스를 정립하고 폭발압력의 상호작용 분석을 위해 LS-DYNA를 활용한 유한요소해석을 수행하여 방호성능평가를 수행하였다.
