高速列车模型实验系统及其测试结果分析

HIGH-SPEED TRAIN MODEL EXPERIMENT SYSTEM AND MEASUREMENT RESULT ANALYSIS

高速列车在进出隧道时 ,会产生一系列气动效应。模型实验是研究这一问题的有效方法。西南交通大学土木学院借鉴国内外的经验 ,研制建立了高速列车模型实验系统。本文对该实验系统进行了介绍 ,并对测试结果进行了分析 ,得出了高速列车在进入隧道过程中 ,压缩波产生、变化的一些规律。

When high-speed train entering and exiting from tunnel, a series of aerodynamics effect was created. Model experiment is efficient methods to research these problems. On analyzing all the model experiment methods in the world, a set of high-speed train model experiment system was built by Southwest Jiaotong University. In this paper, the experiment system was introduced thoroughly. The measurement results were analyzed and some principles on pressure wave creation and transportation were drawn out.
