随着列车速度的增加，空气动力学和气动声学问题变得越来越重要。在日本这样的山区国家，与火车/隧道系统相关的空气动力学问题尤其重要。此外，为了使新干线噪声符合环境标准，降低随列车速度而迅速增加的空气动力噪声变得至关重要。本文讨论了几个空气动力学问题，讨论了这些问题的解决方法、现状和未来展望。
As the train speed increases, the aerodynamic and aeroacoustic problems become more and more important. In a mountainous country like Japan, the aerodynamic problems related to the train/tunnel system are especially important. Moreover, to make the Shinkansen noise conform to the environmental standards, reduction of the aerodynamic noise which increases rapidly with the train speed becomes essential. Several aerodynamic problems are taken up in this paper, and the methods of approach, the present situation and the future outlook of these problems are discussed.
