摘　　要：以上海高速磁浮示范运营线车辆为基础,结合高速磁浮列车技术特点及车辆特性,对列车运行阻力特性和牵引特性进行分析研究。从旅客乘坐舒适性、不显著降低列车运行速度及车站列车悬浮停止安全性角度出发,提出了区间正线及车站正线的最大纵坡建议值。研究结果表明,高速磁浮区间正线最大纵坡能够达到90‰,并且在这样的纵坡上列车仍能保持不低于200 km/h的运行速度;车站正线一般宜设置在平道上,困难情况下可设在不大于4‰的坡道上,以防止列车意外滑动。Based on the vehicle running on Shanghai high-speed maglev demonstration line,also combined with the technical characteristics of the high-speed maglev train and the vehicle characteristics,the running resistance and traction characteristics of the train are analyzed and studied in this paper.Then,from the perspective of passengers comfort and train suspension safety at station without significantly reducing the running speed of the train,the recommended value of the maximum slopes on the main line and station line is proposed.The research shows that even when the maximum slope on the high-speed maglev main line reaches 90‰,the train can still maintain the operating speed about 200 km/h.But to prevent the train from accidental slipping,the station line should be built on flat road,even in difficult conditions,the station line should be built on the ramp no more than 4‰.
