摘要
高速列车在运行时,列车与空气的相互作用十分强烈。在实际的车辆开发研究过程中,随着列车的提速,如何有效地利用空气动力学特性变得愈来愈重要[1]。本文创建了350km/h高速列车编组明线运行的三维计算模型,并建立了头车车下设备舱内部流场的计算模型。对列车在环境温度为40℃～-40℃下,设备舱内的温度分布情况进行了数值研究,获得发热设备表面温度随不同环境温度的变化规律,为车下设备的合理布局提供依据。
When the high speed train in operation, the interactional force between the train and air is extremely strong. In the process of RgaD, along with the ever increasing speed, how to effectively use the aerodynamics characteristics become more and more important. This article aims on numerical value analyzing for the off-vehicle equipment cabin temperature field of a certain kind of high speed train which is working in the open wire condition. Thereby educe the surface temperature changing rule of the radiation equipment in the offvehicle equipment cabin. Thus we can provide foundation for the rational layout of off-vehicle equipment cabin.
