Abstract

Harmful factors such as shock waves and fragments are generated at domestic ammunition testing sites and military shell shooting training sites due to frequent shooting and explosion tests. As a result, complaints from local residents are rapidly increasing, and there is a high risk of damage to facilities and human life. The recently constructed ammunition test site built a test facility for firing artillery and rocket propulsion in a narrow area with a radius of 300 m due to site restrictions, but damage to the facility is accumulating because there is no adequate protective structure. Therefore, in this study, quantitative data on harmful factors such as noise, vibration, shock wave, and thermal effect generated between artillery firing and rocket propulsion tests were measured, and explosion pressure characteristics were analyzed to design a protective structure, and use Autodyn to protect performance. to perform verification.

국내 탄약 시험장과 군의 포탄 사격 훈련장은 잦은 사격과 폭발 실험으로 인해 충격파와 파편 등의 유해인자가 발생한다. 이에 따라 지역 주민의 민원이 급증하고 있으며 근접한 시설물과 인명피해의 위험이 크다. 최근 건설된 탄약 시험장은 부지확보 제한에 따라 반경 300 m 이내의 좁은 지역에서 화포 사격 및 로켓 추진기관 연소시험 시설을 구축하였으나 적절한 방호구조물이 없어 시설물 피해가 누적되고 있다. 따라서 본 연구에서는 화포 사격 및 로켓추진기관 실험 간 발생하는 소음, 진동, 충격파, 열 효과 등 유해인자에 대한 정량적 데이터를 측정하고 폭발 압력 특성을 분석하여 탄약 시험장의 강재 방호구조물 적용 연구를 수행하였다.
