Abstract

As the number of hydrogen filling stations for hydrogen supply increases with the progress of low-carbon eco-friendly energy policies, the risk of accidents is also increasing. Actual pressure vessels may have defects such as notches, pores, and inclusions that may occur during the manufacturing process. Therefore, it is necessary to evaluate the integrity of pressure vessels in the case where cracks exist in pressure vessels under internal pressure. In this paper, 3D finite element analysis was used to evaluate the structural safety of hydrogen-filled pressure vessels with surface cracks, and the shape of surface cracks was compared with the commonly used semi-elliptical shape. In the future, these results will be used to predict the remaining life of the pressure vessel in consideration of fracture mechanics.

저탄소 친환경에너지 정책이 진행으로 인해 수소 공급을 위한 수소충전소의 증가됨에 따라 사고발생 위험도 커지고 있다. 실제 압력용기는 제조과정에서 발생할 수 있는 노치와 기공, 개재물 등의 결함이 존재할 수 있다. 따라서 내압이 작용하고 있는 압력용기에 균열이 존재할 경우에 대한 압력용기의 건전성을 평가하는 것은 필요하다. 본 연구에서는 표면균열이 있는 수소충전용 압력용기의 구조안전성을 평가하기 위해 3차원 유한요소해석을 이용하였으며, 표면균열의 형상은 일반적으로 많이 사용되는 반타원 형상을 적용하여 균열의 형상 및 응력비에 대한 균열진전 특성을 비교하였다. 향후, 이러한 결과를 이용하여 파괴역학을 고려한 압력용기의 잔존수명 예측에 활용할 예정이다.
