摘要
客车的空气动力性对其动力性、经济性和稳定性有极其重要的影响。本文利用CATIA软件对某客车进行三维建模,并利用流体动力学分析软件Fluent对客车外流场进行数值模拟,对分析结果进行可视化分析,并提出优化方案。
Aerodynamical performance of coaches has an extremely important impact on its power, economy and stability. The Three-dimensional modeling of coach based on CATIA is proposed in this paper, then numerical sim- ulation of out flow field using fluid dynamics analysis software Fluent and visual analysis are done. Finally the opti- mization program are presented.
