| 摘 要： | 为减少钝头列车的气动阻力,对车头圆顶、车体底罩、车间风挡的假想模型进行数值模拟计算。结果表明:钝头列车加装车体底罩及车头前部圆顶等结构,并以高于100km/h的速度运行时,减阻效果良好,行驶速度越高,减阻效果越明显。

| Abstract: | According to the models of a certain blunt train surface structure through add-assembly,simulating calculation of it＇s aerodynamic drag under different velocity.The results show that the better add-assembly method is adding bottom cover and dome for the train when the train＇speed higher than 100km/h;the higher running speed,drag reduction effect is more obvious. |
