轻轨车辆的车体材料探讨

Discussion of Light Rail Vehicles Body's Materials

介绍了轻轨车辆的现状、发展历史及其车体承载结构用材料的特点,基于轨道车辆车体材料(普通碳素钢、耐候钢、不锈钢、铝合金及航空复合材料)的技术性和经济性的比较,指出铝合金是目前生产轻轨车辆较为合适的材料,同时对新型航空材料的使用前景进行了展望。

The development course and present situation of light rail vehicles at home and abroad were introduced in this paper. At the meantime, based on comparing the technical an economical features of weather-carbon steels, resistant steels, stainless steels, aluminium alloys and aero compound materials, pointed out that aluminium alloys are suitable to car body material of LRV. Furthermore, prospects of aero compound materials＇ use were looked forward to.
