摘要
为研究在平坦空旷地区横风对电动车组中各车辆气动特性的影响，在８ｍ×６ｍ风洞中对三车联挂的电动车组模型进行测力试验，并对试验数据进行分析，认为横风风速为１５ｍ／ｓ～２５ｍ／ｓ、列车速度不大于３００ｋｍ／ｈ时，横风不能吹翻列车，电动车组横向是稳定的。
In order to study how the cross winds in flat open country affect the aerodynamic characteristic of each EMU vehicle,experiment of EMU model composed of 3 vehicles is conducted in a 8 m×6 m wind tunnel,the author analyzes the data of the experiment,concluding that when the cross winds speed is in the range of 15 m/s～25 m/s,the EMU train set is stable laterally with running speed not higher than 300 km/h.
