摘要(Abstract)：

探讨了高速动车换气口流动阻力实验台相关问题,根据流体力学相关原理,提出用低速风洞模拟列车外界风速场,换气口试件置于风洞试验段中,将列车外界风速、流经换气口的风量模拟量都设计成可调控的实验参数,搭建了用于换气口流动阻力及其影响因素的实验平台。实验实例表明,本文方法建立的高速动车换气口流动阻力实验台方案是可行的,测量结果是可信的。
Problems about an experimental platform are discussed,recurring to which,the flowing resistance of air vents on the bullet train can be researched.According to the principle of fluid mechanics,it is put forward that the train wind field outside can be simulated by the low speed wind tunnel,the ventilation test piece is placed in the test section of wind tunnel,the wind speed outside and the flowing rate through the air vents are tunable,then a experimental platform for flowing resistance of air vents is built.The experimental results show that the scheme of the experimental platform is feasible,and the measurement results are credible.
