| Abstract: | 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. |
