摘要
阐述了对我国首列200km/h动力分散型电动旅客列车组(先锋号列车)车体表面压力分布测试情况,对测量结果进行了较为详细的分析,最后用流场计算软件CFX对先锋号列车周围流场进行了数值模拟计算,并将计算结果与测量结果进行了对比,两者有较好的一致性。该研究结果可为空调装置及电器设备冷却风道进排风口位置的选取提供科学依据。
In this paper it is elaborated the investigation of the pressure distribution on external surface of the first electric passenger train of scattered power at a speed of 200km/h of China(Xian Feng train).The result of measurement has been analyzed in detail. In the end the writers used CFX, the computing software for flow fields, to compute the flow fields around Xian Feng train. While compared the result of numeric computation with measurement, both results are in good agreement. The results of this research lay the foundation for choosing the position of entrance or exit of wind of air conditioning and cooling pipe of electric equipment.
