Pressure Analyses of Instant Turbulence and Vibration between Two Passing High-speed Trains
In this study, we aimed to mitigate the turbulence and vibration effects encountered when two high-speed trains pass each other by employing the software Ansys Fluent for simulations.By comparing the simulation results with existing literature on the interaction of high-speed trains passing alongside each other in various environments, we evaluated whether the established simulation model accurately reflects real-world pressure curves measured by sensors during the passing moment.To minimize the turbulent effects while the trains are in motion, we investigated the feasibility of installing stabilizing flow wings on the exterior of the front end of the trains.The objective was to determine whether these modifications could effectively reduce turbulence and improve train stability.The research included simulations where different configurations of stabilizing flow wings were tested, such as various widths, lengths, quantities, and positions of the wings.These different designs were simulated to evaluate their impact on reducing turbulence during train interactions.The findings suggest that adding stabilizing flow wings to the front ends of the trains can reduce the turbulence-induced effects by approximately 37% when two high-speed trains pass each other.This reduction in turbulence can lead to improved safety, comfort, and operational efficiency for high-speed rail systems, particularly in environments where high-speed trains frequently encounter each other.
