The effect for tunnel section area to running resistance of high speed train

Last updated on 06 March 2020 12:23

Aerodynamic drag has great effect on maximum speed as well as the energy consumption of the highspeed train because its occupation in running resistance gets larger as train runs faster. And it is also well known that the running resistance in tunnel is much larger than that in open air...
