A Comparative Study on the Design Techniques of Metal and Hybrid Composite Carbody Structures in Railway Vehicle System

금속재 차체와 하이브리드 복합재 차체와의 설계기술 비교 연구

There are the marked differences between the design techniques of carbody structures made of composite materials and metal materials. The design techniques of carbody structures made of metal materials have already been guaranteed in the domestic field. But, in case of the hybrid composite carbody structures, it is the first attempt to be developed and there is no experience of the design in the railway applications. In this paper, the design techniques of hybrid composite structures were introduced and compared with that of the conventional metal carbody.
