Analysis of Train Safety Marking Settings Based on Bernoulli’s Principle

Abstract

With the process of urbanization and the rapid development of China’s railways, the safety of passengers on the platform has received widespread attention. The purpose of this paper is to study the “suction” or “thrust” caused by trains and subways when passing through the platform through mathematical modeling, and to further analyze the basis for the setting of safety markings, so as to put forward suggestions to ensure the safety of railway platforms. In order to solve this complex problem, a theoretical model based on Bernoulli’s principle is established to quantitatively describe the “suction” or “thrust” caused by the air pressure change caused by the operation of trains and subways to the platform passengers, and then the safety factor is introduced to consider passengers of different heights and weights. Then, the factors aff ecting the safety distance of the railway platform are found, the influence of various factors on the safety marking setting of the railway platform is analyzed, and some suggestions are provided according to these factors to ensure the safety of the railway platform, and the system optimization method is used to form a comprehensive understanding of it and make improvements. In summary, by comprehensively considering multiple factors such as train running speed, platform design parameters, passenger density and safety standards, a series of suggestions to improve the safety of railway platforms can be put forward to ensure the safe travel of passengers.
