指出了提速机车的行驶风速已达１２级强台风，提速对机车涡轮增压柴油机增压压力的影响不容忽视；分析了行驶风速与绕流机车气流压力的关系；探讨了提速对涡轮增压柴油机增压压力影响的途径，并以能量守恒、质量守恒为依据，导出了行驶风速对增压压力影响的关系式。
It is pointed out that the driving speed of the locomotive has reached 12 typhoon. The influence of speed increasing on the turbocharged diesel locomotive supercharging pressure can not be neglected. The relationship between driving wind speed and the pressure of locomotive around the locomotive is analyzed. The way of the influence of supercharging pressure and the relationship between the driving wind speed and the supercharging pressure are derived based on the conservation of energy and the conservation of mass.
