摘 要:我国城市轨道交通在上世纪90年代以后得到迅速发展,A、B型地铁车辆在各大城市得到了广泛应用,跨座式单轨交通车辆和低地板车辆也投入了运营。城市大力发展轨道交通,其车辆需求量剧增,车辆国产化意义重大。指出我国城轨车辆的平均国产化率在逐步提高,尤其在电传动及其控制系统和制动系统国产化方面取得了长足的进步。Ever after 1990 the domestic mass transit has been developed quickly. Metro vehicles of type A and B have been applied widely in big cities. Single-rail vehicles and low-floor vehicle have been put into operation as well. Fast development of mass transit leads to vastly increased demand of vehicles. And the localization of vehicles makes great sense. It is pointed out that the average localization rate of domestic mass transit vehicles is increased. Greater improvement has been made in the localization of electric drive system, control system and brake system.
