Description
Technical Field
The utility model belongs to car bottom air guiding device field relates to a van air guiding device and applied device's van.
Background
With the development of automobile technology and highways, the running speed of automobiles is increased day by day, and the aerodynamic resistance of the automobiles interacting with air is more and more obvious when the automobiles run, which influences the economy, dynamic property and stability of the automobiles to a great extent. The automobile aerodynamic numerical simulation is developed rapidly, and the aerodynamic performance is optimized, so that the air resistance coefficient is reduced, the fuel economy is improved, and considerable economic benefit can be generated.
During the running process of the truck, the air resistance suffered by the truck is composed of four parts: 1. the surface resistance refers to the frictional resistance generated when the air flow passes through the outer surface of the vehicle, and the resistance is mainly caused by the interference of the vehicle body shape and parts arranged outside the vehicle body, such as rearview mirrors, vehicle door handles, vehicle lamps, vehicle head decorating parts and the like on the air flow, particularly the transverse resistance generated by the air flow from the two sides of the semitrailer on the vehicle, and the resistance can greatly affect the vehicles with the same size, such as semi-trailers and buses. 2. The pressure difference resistance and the magnitude of the pressure difference resistance depend on the size of the turbulent flow area, particularly the size of the tail turbulent flow area. Where the gas flow becomes turbulent, a partial vacuum region is created, thus creating a pressure differential resistance. In truck design, designers need to strive to reduce the turbulence surface, and thus the vacuum area. 3. The induced resistance, which is a part of the differential pressure resistance, is caused by the difference in air pressure between the top and bottom during the running of the vehicle, and the differential pressure resistance and the induced resistance account for the largest proportion of the total air resistance. 4. The in-vehicle resistance is resistance caused by the air flow through a radiator, an engine, and the like in the vehicle head. In summary, installing the flow guiding devices on both sides of the van is one of the important ways to reduce the wind resistance of the van.
It has been confirmed that when the vehicle is running at a high speed, the maximum resistance is derived from air, and the higher the vehicle speed, the greater the air resistance the vehicle is subjected to, and the increase in air resistance is proportional to the square of the increase in vehicle speed. Experiments have shown that almost half of the fuel consumption is used to overcome the air resistance when the vehicle speed is higher than 80 km/h.
Nowadays, energy is increasingly tense, oil price is continuously increased, and how to reduce fuel consumption becomes the key point of attention of automobile manufacturers and users. Reducing the wind resistance and the dead weight of the vehicle is an important way for improving the competitiveness of products.
