高速磁浮明线越站安全门参数对站台列车风的影响
Influence of safety door parameters on train-induced wind at the platform during high-speed maglev passing in open air
摘要
Abstract
To enhance the safety of platform areas during the passage of a high-speed maglev train,a ground-level island platform station was taken as the prototype,and three-dimensional numerical simulations were conducted to investigate the effects of safety door height and the distance between the safety door and the platform edge on train-induced wind velocity when a high-speed maglev train passed through the station at 600 km/h.A critical design curve for safety door parameters was established based on a safety wind speed threshold of 14 m/s.The results show that,as the safety door height increases from 1.6 m to 2.4 m,the wind velocity in the pedestrian activity zone(z≤2 m)decreases significantly,with a maximum reduction of 72%,whereas in the equipment installation zone(z=3 m)the wind velocity exhibits an increasing trend,with the maximum increase of 71%,demonstrating that the influence of safety door height varies markedly with vertical position.When the distance increases from 0 m to 1.2 m,the wind velocity near the measuring points at the safety door decreases by up to 36%;as the measuring points move away from the safety door,the wind velocity differences among different cases gradually reduce to within 2 m/s,indicating that the influence of safety door distance is primarily confined to the vicinity of the safety door.The critical design curve based on the safety wind speed threshold shows that,when the safety door distance is 0 m,the safety door height is required to be at least 2.1 m to satisfy the safety requirement in the pedestrian zone.When the safety door height is 1.6 m,the safety door distance must be no less than 0.6 m to maintain the wind velocity below the safety threshold;and the findings provide theoretical and engineering support for the design of safety doors in high-speed maglev stations.关键词
