| Abstract: | The measuring method investigation on the cooling fan flowrate of the traction motor of the 270km/h high speed train through ground standardizing tests is performed. The relation between the Pitot tub dynamic pressure or total pressure of the fan and the fan flowrate is obtained by tests. The investigation results show that the measuring flowrate methods using Pitot tub and total pressure of the fan are adaptive to measure the air volume of the cooling fan air flow during the train running process. |
