| 摘 要： | 基于 CFD 数值模拟方法, 采用“动网格”技术, 对列车高速过站(80 km/h)风环境进行数值模拟, 给出高速列车开始驶入、完全驶入和驶离车站时, 站台区域行人高度风速变化情况。在站台行人区域布置63 个风速测点, 对列车风的影响进行定量评估, 并结合评定人员活动的风环境舒适度评估标准, 划定站台区域人员活动安全和舒适范围, 为站台区域设计提供建议。

| Abstract: | Dynamic mesh method based on numerical simulation method of CFD was adopted. The changes of wind velocity in pedestrian level were calculated when the train entered, passed through and left the station at high speed (80 km/h). 63 monitor points at the pedestrian height were arranged to assess the influence of train wind quantitatively. The range for the pedestrian safety and comfort were given based on the proper wind comfort criteria, which could provide useful guide to platform design |
