Abstract

Trains on the move create disturbances in the surrounding air that provides the flow over the entire length of the moving vehicles. With the ever-increasing speed of the trains, this issue has become more imperative. When a high-speed train passes near the structures such as the tunnels, bridges, etc. interaction between the moving train and the structures generates noise flow around the train that is in turn responsible for the creation of pressure waves. Such pressure waves can cause detrimental effects on the trains and the track wayside equipment and endanger safety and wellbeing of people that either live or work near the tracks. In this research, with the review and evaluation of the trains' Aerodynamic standards the issue of the effects of the Crosswinds on the running safety of the high-speed trains is studied. By simulating the effects of the Crosswinds on the Aerodynamic behavior of the high-speed trains in the speed range of 160-300 km/hr, some of the parameters that are vital for the train dynamic safety are considered. Also, some propositions for increasing the train running safety and improving its ride and dynamic behavior are suggested. When the flow of wind is perpendicular to the direction of the train travel, it can cause deterioration of the train travel safety. Such issues are investigated in this research and some practical technical remedies are offered. It needs to be reminded that the high-speed trains do not operate in Iran. Therefore, these types of studies have never been performed. However, within the countries that already have the high-speed train systems, such studies, in the past and present, are quite common.
