유한요소 해석을 이용한 연료 전지 차량용 Type 2 복합재 압력용기의 경량화 최적 설계 = Design Optimization of Type 2 Composite Overwrapped Pressure Vessel for Fuel Cell Vehicle using Finite Element Method

국문 초록 (Abstract)

최근 수소 연료 전지 자동차의 주행 거리 증가를 위해 수소 저장용 복합재 압력용기의 경량화 설계가 요구되고 있다. 본 논문에서는 수소 연료 전지 자동차의 주행 거리 향상을 위해 70MPa 156.6L급 수소 저장용 type 2 복합재 압력용기의 경량화 최적 설계를 수행하였다. ASME 설계식과 위상 최적화를 통해 금속 라이너의 형상을 결정하였으며 복합재의 경량화를 위해 형상, 두께, 적층 순서를 최적화하였다.

다국어 초록 (Multilingual Abstract)

Recently, the need for development of light weighted pressure vessel for hydrogen has increased to extend driving range of fuel cell electric vehicles. In this paper, the design optimization of 70MPa 156.6L hydrogen composite pressure vessel was conducted to minimize its mass. The shape of the metal liner was determined through the ASME design formula, and topology optimization. The design of composite reinforcement such as shape, thickness, and stacking order has been optimized to reduce the weight of the composite.
