Aerodynamic Phenomena Caused by the Passage of a Train. Part 1: Pressure Interaction With Objects

Abstract

The series of articles describing aerodynamic phenomena caused by train passage characterise the interaction of a train travelling at high speed with the moving train itself, on other trains, on trackside objects and on people. This interaction can be of two types – generated pressure and slipstream. Apart from the literature analysis, the author’s research was also taken into account. The first part presents the general classification of aerodynamic phenomena, the pressure change wave-form in open space caused by the passage of a train and the pressure interaction with trackside objects. Conclusions are presented on the construction of a high-speed rail vehicle and the strength and location of structures on high-speed lines. Keywords: rolling stock, high-speed railways, aerodynamic phenomena
