摘　　要：以B型地铁列车为研究对象,通过对地铁列车空调系统和车厢内部空气组织的初步调查,采用理论定性分析和CFD数值模拟两种的方法对地铁车辆的空气分布进行了分析。在现有的理论基础上,对B型地铁列车进行分析,提出了在送风道中增加调节板,以保证列车各出风量的均匀,通过模拟仿真得出在增加调整片后,进气口端的风量显著增加,末端风量减小,各个出风口的出风量相对均匀,各风道压力分布较为均匀。In this paper, type B subway train as the research object, through the preliminary investigation of the subway train air conditioning system and the air structure inside the carriage, using two methods of theoretical qualitative analysis and CFD numerical simulation to analyze the subway vehicle air distribution. On the basis of the existing theory, the paper analyzes the B-type subway train, and proposes to add a regulating plate in the air supply duct to ensure the uniform air volume of each train. Through the simulation, it is concluded that after adding the adjusting plate, the air volume at the intake port increases significantly, the air volume at the end decreases, the air volume at each outlet is relatively uniform, and the pressure distribution in each air duct is more uniform.
