摘要
在汽车保有量不断增长以及国家“双碳”目标的大环境下,汽车低碳化发展带来的汽车降阻问题成了汽车研究的重点。阐述了国内外汽车空气动力学研究现状及汽车风阻系数上的差距,梳理了空气动力学套件在外饰上的应用。指出目前国内空气动力学研究大多处于探索阶段,研究方向及研究手段基本参考国外,研究深度不足且无统一的空气动力学理论指导。未来空气动力学研究应侧重造型变革,发展新的降阻技术,建立空气动力学理论。
In the context of the continuous increase of car ownership and the national "Double Carbon" goals, the reduction of the drag coefficient caused by the low carbon development of automobile has become a major research topic for car manufacturers. In this paper, the research status of automobile aerodynamics at home and abroad and the gap in drag coefficient of automobile at home and abroad are described. This paper describes the research status of automobile aerodynamics and the gap in drag coefficient at home and abroad, and combs the application of aerodynamic kits in exterior decoration. It is pointed out that at present, the domestic aerodynamic research is mostly at the exploratory stage, the research direction and means basically refer to foreign research, the research depth is insufficient and there is no unified aerodynamic theory guidance. It is suggested that future aerodynamic research should focus on modeling reform, develop new drag reduction technology, and try to propose aerodynamic theory.
