基于内外流场仿真分析对整车性能研究和优化

The Analysis and Optimization of Vehicle on Numerical Simulation of flow field

采用STAR-CCM+软件对汽车内外流场进行仿真分析,判断影响整车性能的布置和造型设计要素。在整车开发设计阶段,通过对机舱内外气体的模拟仿真,得出造型及布置是否满足外部流场压力和舱内进风量设计要求,是否满足整车动力性、经济性等指标。

Simulation analysis of the full flow field of a passenger vehicle by using STARCCM＋. We can determine the layout and design elements that effect vehicle performance Whether to meet the vehicle power and economic indicators should be estimated according to simulation results. Those results can provide the basis of the further optimization of engine bay arrangement and styling in the design.
