REVIEW OF AERODYNAMIC INVESTIGATIONS FOR HIGH SPEED TRAIN

随着我国高速铁路的快速发展,高速列车运行速度越来越快,包括气动阻力、横风效应、会车效应、隧道效应和气动噪声等一系列空气动力学问题日益突出.利用模型试验、实车测量和数值计算等不同的研究手段,开展全面的高速列车空气动力学研究显得十分重要.本文比较全面和系统地介绍了国内外高速列车空气动力学研究在模型试验、实车测量、数值计算等方面的技术现状和进展情况,对今后的发展方向和内容进行了展望.

With the fast development of the domestic high speed railway, the very high running velocity of the trains causes a series of aerodynamic problems, including the problems of the aerodynamic drag, the cross wind effect, the train passing effect, the tunnel effect and the aerodynamic noise. It is very important to combine various investigation technologies, such as the model testing, the real train measurements and the numerical simulation to study the aerodynamics of the high speed train. This paper reviews the domestic and overseas aerodynamics studies of the high speed train, and the development directions.
