摘　　要：利用Fluent软件对受电弓导流板涵道式翼形气动特性进行了二维数值研究,观察了不同涵道位置情况下导流板翼形周围流场的压力分布和速度分布,求出了各情况下导流板受到的升力及阻力,最后对受电弓稳定受流的气动补偿控制做出可行性预测。Abstract Fluent software is used for the study of 2 - D numerical simulation on thc aerodynamic characteristic of culvert airfoil, the static pressure and speed distributions of the airflow field surrounding the airfoil under different vertical positions of culvert are monitored. Then the lift force and drag force acting upon the air deflector in each position is calculated, thc result leads to a feasibility prediction on the aerodynamic air supply control of pantograph＇s air de- flector in order to ensure the stable power- receiving.
