摘要	The high-speed trains have very complex running environments, which contain single-train running in open air, two-trains passing by in open air, single-train running in tunnel and two-trains passing by in tunnel. As the environment wind appears, cross-wind effect must be considered. Aerodynamic design of high-speed trains mainly aims at the drag, lift, moment, impulse pressure waves, aerodynamic noise etc at typical running conditions. In the paper, the aerodynamic design processes of CRH380A and 380B are introduced and the aerodynamic performances of different designs are emphatically analyzed and compared. Wind tunnel experiments and running tests indicate that the new generation of high-speed trains holds excellent aerodynamic performances.
