| Abstract: | With the development of metro train, the speed of metro train is also increasing. The aerodynamic characters of metro train is becoming more and more important. The aerodynamic model of flow outfield metro train is built in this paper. The distributing of air flow around metro train head is calculated and analyzed. According to the requirements of aesthetical design of metro train head, a design scheme which has 48o obliquity of fi＇ont window is presented to meet the harmonious design between aerodynamics and aesthetics. |
