摘　　要：针对高速列车气动性能,探讨一种列车车头外形优化仿真方法,利用优化软件Sculptor对某高速列车车头司机室观测窗处曲面进行重构,并运用流体数值仿真软件Fluent对重构模型进行数值模拟,计算结果显示,降低司机室观测窗处曲面的高度,有利于降低列车的气动阻力.A new simulation method is employed to optimize the surface of high-speed train front for improving aerodynamic performance, the surface at observation window of the cab is reconstructed by using optimization software Sculptor, and the fluid dynamics simulation software Fluent is used to simulate the reconstructed mod- el, calculation results show that reducing the surface height at observation window of the cab is in favor of re-ducing aerodynamic drag of the train.

关 键 词：气动性能 曲面重构 数值仿真 优化 SCULPTOR
