Abstract

With the continuous increase in the speed of high-speed trains, the comfort, stability and safety of high-speed trains have gradually become the focus of attention. Crosswind has an impact on the safety and comfort of high-speed train operation, and it is a research object that needs to be given priority. This paper considers the influence of crosswind on high-speed trains and uses the research method of simulation analysis to numerically simulate the aerodynamic performance of the cross-sectional shape of the high-speed train body. By comparing and analyzing the force conditions of different geometric shapes of the high-speed train body cross-section under crosswind, the optimal cross-sectional shape of the high-speed train body is obtained, providing a basis for the further development of the shape design of high-speed trains.
