Recent Studies on Aerodynamic Characteristics of Railway Vehicles

Abstract

Aerodynamic phenomena concerning railway vehicles relate to various issues on railways. The improvement of aerodynamic characteristics of railway vehicles could enhance the value of railway from the view point of safety, convenience, comfort, harmony with the environment, cost reduction, etc. This paper describes the outlines of recent studies on the aerodynamic characteristics of railway vehicles conducted by the Railway Technical Research Institute such as stability against cross wind, air resistance, lateral motion in tunnels and aerodynamic noise.
