복합재료를 적용한 한국형 고속틸팅열차(TTX)의 차체 구조해석 연구

The use of composite materials for the carbody structures of tilting train has many advantages because of manufacturing variety, specific high-strength & stiffness characteristics, and long-life durability, but the strongest advantage is the possibility of lightweight product. In the leading countries, the composite materials are used for the material for drivers' cabs, interior/exterior equipments for railway train, and it is now developing the composite materials applied for the train carbody structure. In this paper, we conducted the evaluation of structural stability for the all aluminum carbody, all composite carbody and hybrid carbody structures of the Korean Tilting Train eXpress(TTX) with the service speed of 180㎞/h.
