高速客车模型气动特性实验研究

介绍了高速客运列车模型气动特性在低速风洞中测量结果.试验模型由头车、中间车、尾车模型组成,且头、尾车互换位置.试验风速为80～300km/h,风向角为0°.同时还进行受电弓接触压力测量.试验结果表明:不同头车和尾车组合,对高速客车的气动阻力有很大影响.整流罩和受电弓使列车空气阻力明显增加.

An experimental research of aerodynamic characteristics of the high speed passenger train model

The measurement results of an aerodynamic characteristics on high speed passenger train model in low speed wind tunnel are introduced.The test models include a head train,a middle train,a tail train and a model exchanged between a head vehicle and a tail one.The test wind velocity ranged from 80 km/h to 300 km/h,and the direction angle of wind was zero degree.At the same time,the dynamic touch pressure survey on the pantograph was also conducted.The measurement results indicate that the different combinations of the head and tail vehicle have obvious effect on an aerodynamic drag of the high speed passenger train.The total aerodynamic drag of the train with the rectifying cover and pantograph is evidently increased.
