摘 要:通过提取高铁站典型门斗参数,构建了动态拓扑的参数化几何模型。在此基础上提出新型平面形式,利用FLUENT仿真平台对3402个门斗样本进行多风速风向条件下的抗冷风优化选型研究。用防风效率评价不同类型门斗以及防风构件的抗冷风性能,得到不同风速风向下各空间参量对防风效果的贡献率。结果表明,止回阀型门斗抗冷风效果最佳,平均防风效率为21.70%,结合安检型门斗的平均防风效率为15.36%,角涡流型门斗的平均防风效率为13.92%;导风板与止回阀顶棚构成的组合构件对双层门斗的平均防风效率提升了2.03%,对3层门斗提升了4.72%。该研究提出高铁站门斗空间参量以及构件的防风优化选型策略。A parametric geometric model with dynamic topology is constructed by extracting typical door bucket parameters of high⁃speed railway stations.On this basis,a new planar form is proposed,and the optimal cold wind resistance selection study is carried out for 3402 door hopper samples under multiple wind speed and wind direction conditions using FLUENT simulation platform.The wind protection efficiency is used to evaluate the cold wind resistance performance of different types of door buckets,and the contribution rate of each spatial parameter to the wind protection effect under different wind speeds and directions is obtained.The results show that the check valve type door bucket has the best cold wind resistance with 21.70%wind protection efficiency,combined with the security check type door bucket with 15.36%wind protection efficiency and the angle vortex type door bucket with 13.92%wind protection efficiency;the combination of wind guide and check valve canopy improves the average wind protection efficiency of the double⁃layer door bucket by 2.03%and the three⁃layer door bucket by 4.72%.The study proposes the optimal windproof selection strategy for the spatial parameters and components of the door bucket of the high⁃speed railway station.
