摘　　要：根据对２００ｋｍ／ｈ电动旅客列车组控制车进行的小模型风洞试验所得结果，分析了在头部长度相同时头部外形变化、风挡、车体底罩对列车运行空气阻力的影响及头部形状、线间距对列车交会压力波的影响。In light of the results obtained in the small air tunnel test for the control car in the 200 km/h electrical passenger train unit,analyzed are the effect of the contour changing,vestibule diaphragm and carbody bottom cover on the air resistance during running of the train while the length of the car head being equal,the effect of the distance between the tracks and the head contour on the pressure wave during crossing of two opposite trains.
