高速列车空气动力学性能计算
Calculation in Aerodynamics Performance of High Speed Trains
【摘要】 采用映射法生成高速列车四边形贴体网格及外部流场计算六面体网格;在200km/h和300km/h2种工况下,对高速列车的空气动力学性能进行了计算,得出了表面压力的分布状况;对高速列车车头曲面关键点的压力进行了实车测试,验证了计算结果的正确性。
【Abstract】 The mapping method is used to make the quadrilateral body fitted grid and the hexahedron grid of outside flow field. Under the two working conditions of 200 km/h and 300 km/h,the aerodynamics performance of high speed trains is calculated,the distribution of surface pressure is obtained; The pressures at key points on the curved surface of the front part of a high speed train are measured on real trains,and the correctness of the calculation results are verified.
