Abstract: The piston wind and the piston effect, which will be produced when the subway enters or leaves the subway station, have close relationship with the ventilation of railway tunnel and energy consumption of the subway. With the wide application of underground rail transit, how to save energy and money as possible, with the comfort of the stand halls and the platform layers, is a question that the construction and management apartment have to consider. Therefore, the rational utilization of piston wind has important theoretical and practical significance to achieve saving energy consumption in railway transportation. Starting from the causes of piston wind, the factors which influence the size of piston wind was studied systematically. And SES simulation was carried on to explore influencing reasons of the piston wind, and a better choice of the piston wind was pointed out. Rational utilization of piston wind is not only good to achieve further energy-saving effective way, but also provide the theoretical support and provide technical reference for subway design and operation.

摘要： 地铁列车在进站或驶离车站过程中产生的活塞效应及其活塞风与地铁通风和能耗关系密切。随着地铁的广泛应用，如何在保证满足站厅和站台层舒适度要求的前提下，尽可能的降低能耗，减少运行费用，是建设和管理部门必须考虑的问题。所以有关活塞风的合理利用对于实现地铁运营节能具有重要的理论价值和实际意义。从活塞风的成因出发，系统的研究了影响活塞风成风大小的因素，对影响活塞风成风的主要因素进行了SES单因素模拟试验，并指出活塞风成风因素的优化选择。这既是合理利用活塞风以实现进一步节能的有效途径，也为地铁设计和运营提供理论上的支持和技术上的参考。
