Model Experiment System for High-Speed Trains and Analysis of Its Similarity

  • Publish Date: 25 Feb 2004
  • 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 trainswhen they pass through a tunnelwas measured using this experimental system. Comparison between experimental and numeral simulation results shows that the similarity rules are correct.
