摘要:
为清晰掌握动车组在极端温度和恶劣风环境下设备舱内沙尘的流向情况，采用列车空气动力学的数值计算方法，对不同恶劣风环境和高温条件下动车组设备舱内流场进行研究。通过对动车组设备舱内压力场和速度场流向的分析比较，获取了动车组在不同车速和不同风速下，其设备舱内流场变化情况，以及底部开孔对设备舱内流场的影响。
Abstracts:
In order to clearly grasp the flow direction of dust in the equipment compartment of EMU in extreme temperature and severe wind environment, the numerical calculation method of train aerodynamics is used to study and analyze the flow field in EMU equipment compartment under different severe wind environment and high temperature conditions. Through the analysis and comparison of the flow direction of pressure field and velocity field in EMU equipment compartment, the change of flow field in EMU equipment compartment at different train speed and under different wind speed conditions, and the influence of bottom hole on flow field in equipment compartment are obtained.
