摘　　要：文章以某中低速动车组为研究对象,建立列车的三维模型,利用计算流体动力学模拟列车在160、200、250 km/h速度下空调冷凝器通风口的压力分布情况,并对压力分布规律进行详细分析,最后基于空调冷凝器风机的不同工作模式对冷凝器通风口结构进行优化。Taking a medium-low speed EMU as the research object, this paper establishes a three-dimensional model of the EMU, and uses computational fluid dynamics to simulate the pressure distribution of the air conditioner condenser vent at 160 km/h, 200 km/h and 250 km/h, and analyzes the pressure distribution law in detail. Finally, the structure of the air conditioner condenser vent is optimized based on the different working modes of the air conditioner condenser fan.
