According to the structure dynamics and the aerodynamics theories, based on and equations turbulent model, the paper deduced metro train head aerodynamic models. On the basis of three new train heads designed by changing the profile or length of longitudinal projection, the outside flow fields around streamlined B-type metro vehicle were simulated with 3-D incompressible viscous fluid theory based on CFdesign software. This paper analyzed theoretically metro train’s physics characteristics in the tunnel, studied its pneumatic idiosyncrasies in running time, calculated its air resistance coefficient, and looked forward to better head sculpt to reduce aerodynamic resistance and filled the metro train heads with beauty and flavor of the times.
