摘　　要：文章以广州某市域快速列车为例,对列车以160 km/h运行在明线和隧道两种场景下的空气阻力进行研究,比较分析了各节车辆及部件的阻力、阻力系数和占比。研究结果表明:市域列车在明线和隧道运行时,头尾车受到的空气阻力最大;在列车各部件中,车体所受空气阻力最大,转向架次之,受电弓最小;隧道运行时列车所受空气阻力达到明线运行时的2倍以上,其中头尾车的空气阻力增幅最大,同时车体、转向架和受电弓的空气阻力也有较大增幅。Taking an urban express train in Guangzhou as an example,this paper studies the air resistance of the train running at 160 km/h on open lines and in tunnels.The resistance,resistance coefficient and proportion of each vehicle and component are compared and analyzed.The research results show that,while running on open lines and in tunnels,the front and end vehicles are subject to maximum air resistance;among the train components,the car body is subject to maximum air resistance,followed by the bogie and the pantograph.The air resistance of the train running in tunnel is more than twice that on open line,and the air resistance increase of the front and end vehicles is the largest.At the same time,the air resistance of the car body,bogie and pantograph also increases greatly.
