摘　　要：因汽车底部的不平整,空气阻力随车速增加而增大,影响车辆的行驶动力性和燃油经济性;高速转弯时升力变大影响汽车的操纵稳定性和安全性。本文设计一种符合空气动力学形状的功能性底盘护板,建立这种功能性护板的物理模型,这种结构保证燃油经济性基础上产生向下方向的压力,提高汽车行驶的操纵稳定性和安全性;提出加装功能性护板后气流经过底盘处解决方案,综合考虑在实际使用中燃油经济性问题。For the bottom of the vehicle is not flat, air resistance increases with the increased speed, and it will affect the vehicle dynamic performance and fuel economy. When in high-speed cornering, the vehicle handling stability and safety goes worse because of the increased air lift. This paper designs a kind of plate which is functional protective, and establish physical model of the functional protective plate. This structure produces a certain pressure to improve the handling stability and safety based on the fuel economy. Considering the problems of fuel economy in actual application, this paper proposed solutions for the airflow through the chassis when adding the functional plate.
