某车型空气动力学性能优化设计研究

Study on aerodynamic performance optimization design of a certain vehicle model

文章根据整车厂开发项目过程中,对整车空气动力学性能进行仿真优化。针对造型面的空气动力学优化的贡献最大,其次是空气动力学套件。其中,散热器导风板不但降低了整车空气阻力,而且增加了散热系统的进气量,整车的动力性经济性得到提升。整车厂在新产品研发过程中,将高度重视CFD仿真的性能优化工作,最大程度为项目降低开发成本,提高整车性能。

According to the development of the vehicle,the aerodynamic performance of the vehicle is simulated and optimized.The most important contribution to aerodynamic optimization is the aerodynamic styling.Among them,the radiator air guide plate not only reduces the air resistance of the vehicle,but also increases the intake volume of the heat dissipation system,and the dynamic economy of the vehicle is improved.In the process of developing new products,the vehicle factory will attach great importance to the performance optimization of CFD simulation,and minimize the development cost of the project and improve the performance of the vehicle.
