摘要
基于现场测试数据,对新型可调通风型屏蔽门系统进行了模拟研究,分析了屏蔽门上方风口三种开启角度30°、60°、90°时活塞风对车站内流场变化的影响,计算了出入口风量,并与地铁设计规范进行了对比。结果表明,60°至90°风口开启角度能够满足地铁设计规范要求,风口角度开启越大,站台层受到活塞风影响越大,开启角度为60°时,活塞风作用于站台区域范围最大。建议可调通风型屏蔽门风口的开启角度在60°至90°范围为宜。
The new type of Platform Screen Door(PSD)system has been simulated,which the air vent on PSD has three kinds of opening angle of 30o,60o,90o.The inward and outward airflow was calculated and compared with the metro design specification.The results showed that this new PSD system are able to satisfy the requirements of the metro design specification when the opening angle is 60oo r 90o,a nd the greater the air vent open,the greater the piston wind effects on the platform.When the air vent open at the angle of 60o,t he affection of the piston wind is the largest.
