ABSTRACT

This article mainly studies the impact of air flow generated by trains entering the station on passengers on the platform, and establishes a relationship model between the air flow velocity and the pressure on passengers during train entry. Firstly, a simplified model of the air velocity around the train was established by combining aerodynamics theory, Bernoulli principle, and relevant formulas, and the air pressure on passengers was calculated. Secondly, the rationality and feasibility of the model were verified through comparative analysis of mathematical models and experimental data. Finally, based on the results of the model, suggestions were put forward for the setting of safety markings for high-speed rail and high-speed train stations, including the relationship between safety distance and train speed, providing theoretical support and practical guidance for station safety management.
