摘要
随着高速列车速度的不断增加,高速列车的气动噪声问题愈发突出。高速列车气动噪声已成为目前世界必须研究和解决的问题之一。针对高速列车气动噪声的性质介绍了高速列车的气动噪声源,分析了受电弓装置、车厢间的连接部位、百叶窗、转向架、车头和车尾各部位气动噪声的产生机理,在此基础上综述了以上各部位降低其产生气动噪声而采取的相应措施。
With the improvement of the high- speed train, the problem of aerodynamic noise generated by high- speed train is standing out.The aerodynamic noise has been one of the problems that many countries all over the world have to research and resolve. On the base of character of aerodynamic noise generated by high - speed train, this paper described the noise sources of high - speed train, and analyzed the mechanism of the pantograph, the inter- coach spacing, the bogie, louvers, the nose and the rear power car, it summarized the ways to reduce noise of the parts by our research.
