摘要
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。
This paper points out that in the speeding up train,for the speed of the driving wind is up to the force 12 typhoon's and the air flow pressure around the train is larger than normal train's,thus the affection of the driving wind to the charging pressure of the locomotive's turbocharge diesel engine can not be ignored.The author analyzed the relations between the driving wind speed with the air flow pressure and discussed the affection ways.According to the principles of power keeping constant and mass keeping constant,the formula of the affection to the charging pressure is led out.
