为研究过渡季可转换式屏蔽门系统在列车活塞风作用下所引入车站的新风量是否能满足要求,以石家庄地铁3号线典型站为例,通过车站内部复杂物体的精确建模、符合实际的车速编程控制、隧道及车站主流区域网格加密等方法,对列车离站过程进行了数值模拟。结果表明,过渡季可转换式屏蔽门系统能满足绝大多数车站新风量的要求,屏蔽门风口尺寸设计是该系统应用的关键因素。
In order to study whether the new air volume of the switchable screen door system introduced by the train piston air during the transition season can meet the requirements, taking the typical station of Shijiazhuang Metro Line 3 as an example, the accurate modeling of complex objects inside the station accords with the reality Speed programming control, the tunnel and the mainstream of the station grid encryption and other methods, the process of train departure from the station were numerically simulated. The results show that the transitional seasonable screen door system can meet the requirements of the vast majority of station fresh air volume. The design of screen door outlet size is the key factor in the system application.
