摘要/Abstract

摘要： 为实现抗风沙型动车组的封闭式设备舱的通风格栅合理布置，建立包含车底设备舱通风格栅和舱内设备的高速列车空气动力学模型，采用CFD方法对高速列车运行时的设备舱流场进行数值模拟，分析格栅布置方式对设备舱通风性能的影响。结果表明：格栅的通风性能主要受格栅布置位置处裙板外侧压力的影响；头车裙板上靠近一位端的位置适宜布置出风格栅，靠近二位端适宜布置进风格栅；中间车裙板上靠近一位端的位置适宜布置出风格栅，其他区域适宜布置进风格栅；尾车裙板上中间区域适宜布置进风格栅、两端适宜布置出风格栅。另外，设备舱底部出风口对其附近的格栅进风性能也有一定影响，设备舱内风机的格栅进风阻力受列车运行速度的影响较小。设计阶段可定性地利用裙板上格栅位置与格栅进排风性能的关系，初步确定适宜的格栅布置方案。

Abstract: To realize the reasonable arrangement of the ventilation grille of the closed equipment cabin of the anti-sand-type EMU, the aerodynamic model of the high-speed train, including the ventilation grille and the cabin equipment is established. The CFD method is used to simulate the flow field of the equipment cabin during the operation of the high-speed train, and the influence of grille layout on the ventilation performance of the equipment cabin is analyzed. The results show that the ventilation performance of the grille is mainly affected by the pressure on the outside of the skirt at the position where the grille is arranged. The position near No. 1 ends of the skirt plate of the head car is suitable to arrange the outlet grille, and the position near the No. 2 ends of the skirt plate of the head car is suitable to arrange the inlet grille. The position near the No. 1 ends of the skirt plate of the middle car is suitable to arrange the outlet grille, and the other region is suitable to arrange the inlet grille. The middle region of the skirt plate of the tail car is suitable to arrange the inlet grille, and the two ends of the skirt plate are suitable to arrange the outlet grille. Besides, the outlet at the bottom of the equipment cabin also has a certain influence on the air intake performance of the grille near it, and the grille intake resistance of the fan in the equipment cabin is less affected by the train speed. In the design stage, the suitable grille layout scheme can be determined qualitatively by using the relationship between the grille position on the skirt plate and the intake and exhaust performance of the grille.
