列车通过隧道诱发的气动变化规律的试验研究

Research on the Variation Regularities of Aerodynamic Events in Tunnels Arising From Passing Trains

以普速钝形列车通过隧道时的列车风和气动压力波的现场运行试验研究为基础，讨论了隧道内列车风和隧道侧壁气动压力波的特性。揭示了带有普遍性的一些规律，为高速铁路隧道空气动力学学科的建设和高速铁路隧道设计提供了部分试验依据。

The research is based on aerodynamic data obtained during the passing of bluff trains' in tunnels at moderate speeds. The paper discusses the characteristics of the flow around train and the aerodynamic pressure fluctuation on tunnel walls, revealing some regular ities and thus providing to some extent test grounds for the design of high speed railway tunnel and the development of high speed railway tunnel aerodynamics.
