The consideration of aerodynamics in the design process of car Fender is mainly reflected in the following aspects.
The first is the outline. The shape of the Fender is usually designed to be streamlined to reduce air resistance. When the vehicle is driving, the air will flow along the body. If the shape of the Fender is abrupt and irregular, it will disrupt the airflow and increase wind resistance. For example, the edge of the Fender will adopt a smooth transition curve to avoid sharp edges and corners. This curve design can guide the airflow to pass smoothly around the Fender and reduce the resistance caused by airflow separation. Just like the edge design of an airplane wing, the carefully designed curve allows the air to flow closely to the surface, thereby improving aerodynamic performance.
The second is the overall integration with the body. The Fender is not an individual independent of the body. When designing, it is necessary to consider its connection with the body. Good aerodynamic design requires a natural transition between the Fender and the body, without obvious gaps or steps. This can avoid the generation of air vortices at the connection, because vortices will increase energy loss and thus increase wind resistance. Designers will use precise modeling and testing to ensure that the installation position and angle of the Fender can match the airflow field of the vehicle body, so that the air flowing through the vehicle body can maintain a stable flow state when passing through the Fender.
In addition, the internal structure of the Fender may also affect aerodynamics. Some Fenders are designed with some guide structures inside, which can guide the air to flow in a specific direction. For example, some small guide plates are set inside the Fender to guide the air to the tires, which plays a role in cooling the tires or reducing turbulence near the tires. This design not only considers the impact of air on the Fender itself, but also considers how to use air to improve the working environment of other parts of the vehicle, thereby indirectly improving the overall performance of the vehicle.
During the design process, the aerodynamic design of the Fender will also be optimized through computer simulation and wind tunnel testing. By simulating the flow of air around the Fender at different vehicle speeds, and testing the impact of different design schemes on vehicle driving stability and fuel economy, the shape, size and internal structure of the Fender are constantly adjusted to achieve the best aerodynamic effect.
