| Abstract | 针对由8辆车组成的CRH3型动车组的实际外形,生成约1.6亿个计算网格,采用大规模并行计算,模拟单列高速列车在明线轨道上以350km/h速度运行时的气流流场,并对列车各组成部分的气动阻力特性进行统计和归类,给出各部件气动阻力对列车总气动阻力的贡献,为高速列车局部减阻优化设计提供参考。 |
| Other Abstract | For the real configuration of CRH3 with the head + six carriages + tail train combination running at 350 km/h in the open air, the flow field was massively parallel-simulated with 160 million of computational grids. The aerodynamic drag of various components was calculated and the component drag contribution to the total train drag was analyzed. The results are helpful to local drag-reduced optimization. |
