Abstract

When developing military equipment, it should be designed considering the temperature condition so that the operator can operate in a stable environment. The shelter for storing various military equipments is operated in various environments. The storage temperature and operating requirements of the test equipment and repair accessories shall be $-32^{\circ}C$ to $50^{\circ}C$ and the inside of the shelter shall be designed to meet the storage temperature and operating requirements. In this study, thermal analysis of a 2.5 ton military shelter operating under high temperature and solar heat conditions is performed considering MIL-STD-810G. The thermal analysis was applied by using the concept of heat resistance and heat circuit, and the solar thermal test was performed on the actually manufactured military shelter in order to verify the analysis results.

군용 장비 개발 시 운용자가 안정적인 환경에서 운용할 수 있도록 온도조건을 고려하여 설계하여야 한다. 각종 군용 장비를 보관하는 쉘터는 다양한 환경에서 운용되고 있다. 시험장비 및 수리부속품의 저장온도 및 운용 요구조건은 $-32^{\circ}C{\sim}50^{\circ}C$로 쉘터 내부는 저장온도 및 운용 요구조건을 충족할 수 있도록 설계되어야 한다. 본 연구에서는 MIL-STD-810G의 기준을 고려하여 고온 및 태양열 조건에서 군에서 운용중인 2.5톤의 군용쉘터의 열해석을 수행하였다. 열해석은 열저항 및 열회로개념을 활용하여 적용하였으며 해석결과를 검증하기 위해 실제 제작된 군용쉘터에 대한 태양열 시험을 실시하여 결과를 비교하여 제시하였다.
