Abstract

By considering the application of RTRI’s detailed equation to Shinkansen, the aerodynamic coefficients and lateral accelerations of car bodies were obtained and verified, taking into account the special geometry of Shinkansen vehicles and their high-speed running. Aerodynamic force coefficients were measured in a wind tunnel test by reproducing the geometry and the running conditions. The lateral accelerations were measured by running the actual vehicle, and it was confirmed that the assumed equation used in the RTRI’s detailed equation can be applied to the Shinkansen. The obtained and verified results were used to evaluate vehicles’ overturning resistance against strong crosswinds of all vehicle types in all sections of the Shinkansen.
