单轨列车车体隔热壁传热系数计算

Calculation of Heat Transfer Coefficient for Insulation Wall of Straddle-type Monorail Vehicle

为使客车车厢的温度保持在一定的范围内,除了安装制冷和加热设备外,还应要求车体具有一定的隔热性能。以重庆轨道交通2号线列车为模型,计算了该车的整车平均传热系数,为车辆设计中计算车体传热系数提供参考。

In order to maintain the temperature of passenger compartments within a certain range,in addition to the installation of refrigeration and heating equipment, the car body is required to have a certain amount of insulation performance. In this paper, the rail vehicle running on Chongqing Line 2 is taken as a model, the average heat transfer coefficient of the car body is calculated to provide a reference for the design process in the future.
