摘要
分析高速列车过站时列车风对站台上方幕墙的影响,采用CFD数值模拟方法,结合"动网格"技术,对列车高速过站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,站台区域幕墙受列车风影响的变化情况。对列车风的影响进行定量评估,研究结果表明:过站列车通过产生的流场对站内风速影响较小,不会对乘客造成安全问题,但该流场对幕墙产生一定的力作用。结论为列车风侧向影响范围最大处出现在头部顶端;列车经行的最不利工况为单线同时对开。
This paper analyzes the impact of the air flow generated by passing high speed train on the curtain wall above the platform with dynamic mesh method based on CFD numerical simulation. The changes of the air flow impact on the curtain wall when the train runs into,at and out of the stationat high speed are simulated and identified. The results show that the impact is minor when the high speed train runs through the station and poses no danger to the pedestrians,but it generates certain force to the curtain wall. It is concluded that peak impact of the train air flow is rested on top of the train and the unfavorable case is when two trains are heading to each other on the single track.
