摘要
为了解决高速列车进出隧道引起的空气动力学问题,基于对目前国内外高速列车模型试验研究现状的分析,建立了模型列车速度可达100m/s的压缩空气式高速列车模型试验系统,并导出了模型试验的相似准则.利用该试验系统对高速列车进出隧道产生的压缩波进行了测试,并将测试结果与数值模拟结果进行比较,验证了相似准则的正确性.
To solve the aerodynamic problems resulted from high-speed trains when they pass through a tunnel, a model experiment system for high-speed trains was set up on the basis of analyzing the relative present experiment systems(methods) at home and abroad, and its similarity rules were derived. In this system, compressed air is used to impel a model train, and the speed of this train speed can reach 70 m/s. The compression wave caused by high-speed trains when they pass through a tunnel was measured using this experimental system. Comparison between experimental and numeral simulation results shows that the similarity rules are correct.
