PRESENT SITUATION AND FUTURE OUTLOOK OF AERODYNAMIC AND AEROACOUSTIC PROBLEMS OF HIGH-SPEED TRAINS

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.
