| Abstract: | 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 model,calculation results show that reducing the surface height at observation window of the cab is in favor of reducing aerodynamic drag of the train. |
