摘　　要：机车司机室的热舒适性对司机的驾驶体验至关重要,本文通过应用CFD仿真分析手段,以空调送风盒的布置作为变量,以司机坐姿头顶区域的温度和速度作为评价指标,对机车司机室的热舒适性进行了深入地分析与优化。结果表面,经过优化设计,司机坐姿头顶区域的平均温度下降了2.8℃,温差减少了4.4℃。同时,最大风速也从3.08 m/s降低到了0.35 m/s,有效地提升了司机室热舒适性,为司机提供了更加舒适的工作环境。The thermal comort in the locomotive driver's cab is crucial to the driver's driving experience.This paper employs Computational Fluid Dynamics(CFD)simulation analysis to deeply analyze and optimize the thermal comfort of the locomotive driver's cab,with the arrangement of the air conditioning supply box as the variable and the temperature and velocity in the area above the driver's seated position as the evaluation indicators.The results indicate that after the optimization design,the average temperature in the area above the driver's seated position has decreased by 2.8℃,the temperature difference has been reduced by 4.4℃,and the maximum wind speed has been reduced from 3.08 m/s to 0.35 m/s.This has effectively improved the thermal environment of the driver's cab,providing a more comfortable working environment for the driver.
