中文摘要：

本文应用LBM（Lattice Boltzmann Method）数值计算方法对列车空气动力制动在不同速度下风翼提供的制动力和在相同列车速度下风翼的形状选择、位置安装以及不同安装数量等情况进行了研究、计算和分析。计算结果为工程设计人员提供了有力的参考依据。

英文摘要：

This paper presented the compute simulation results of the aerodynamic brake.It mainly researched and analyzed not only the brake force provided by the damping vanes on the train at different speeds,but also the damping vanes’ shape selection,the damping vanes’ installation position,and it was installation quantity at the same train speed by using LBM（Lattice Boltzmann Method） numerical calculating method.The calculation result provided engineering designer with powerful references.
