摘　　要：本文提出一种对铁道车辆金属部件是否能用复合材料替换设计的比选方法。利用该方法最终确定了5种车辆部件,即悬臂座椅支架、行李架模块、中间车端墙结构、侧墙结构和车顶结构。在集成潜力、轻量化和商业可行性方面,这些部件被认为是最适合展示复合材料替换金属优势的部件。A methodology used to select and rank those metallic components of railway vehicles suitable for redesign in composite in this paper.five demonstrator components,including cantilevered seat bracket,luggage rack module,intermediate end structure,body side structure and roof structure,were identified using the methodology.In terms of integration potential,lightweighting benefits and commercial viability,these components are considered to be the most suitable components to demonstrate the advantages of replacing metals with composite materials.
