Background technology
In motion, the resistance to be overcome has parts loss resistance, rolling resistance caused by tire (general also referred to as to vehicle
Do roadlock) and air drag.Maximum and most important external force is run into when air drag is running car, with work vehicle
The increase of travel speed, air drag are increasingly becoming most important car resistance, when more than speed per hour 200km/h, air resistance
Power almost accounts for the 85% of all car resistances.
Resistance from air when windage is vehicle traveling, general air drag have three kinds of forms, and first is that air-flow hits
Resistance caused by vehicle frontal, just as being gone against the wind by one piece of plank, suffered resistance is nearly all that air-flow shock is produced
Raw resistance.Second is frictional resistance, and air can produce frictional force as streaking vehicle body, but can be travelled with general vehicle
Prestissimo for, frictional resistance is small to can almost ignore.3rd is outer form-drag, in general, vehicle high-speed row
When sailing, outer form-drag is most important air drag source.As shown in Figure 1 and 2, the resistance caused by external form is from car rear
Region of no pressure, region of no pressure is bigger, and resistance is bigger.In many car conour designs improve, only focus on making for windward side mostly
Type structure, and the structure that have ignored automobile tail is improved, but during galloping, it is formed at the region of no pressure pair of automobile tail
The resistance of automobile is tended to exceed from windward side resistance.
For general vehicle when advancing, the resistance of suffered wind substantially comes from front, unless side wind speed is especially big.Not so not
Vehicle can be had much impact, even if having, can also be corrected by steering wheel.Influence of the windage to automotive performance is very big.Root
According to test, when a car is advanced with 80 km/h, the oil consumption for having 60% is for overcoming windage.Coefficient of air resistance,
Also known as air resistance coefficient, it is a significant coefficient for calculating air resistance of automobile, is to weigh an automobile to be influenceed greatly by air drag
A small standard.It is by wind tunnel experiment and the mathematic parameter determined by experiment that glides, and vapour can be calculated with it
The air drag of car in motion.The size of air resistance coefficient depends on the profile of automobile, and air resistance coefficient is smaller, illustrates it by air
Drag effects are smaller, and vice versa, therefore say that air resistance coefficient is the smaller the better.It is generally believed that the automobile that cleanliness is stronger, its windage
