Background technology
In motion, the rolling resistance that the resistance to be overcome has parts loss resistance, tire to generate is (general to be also referred to as vehicle
Do roadlock) and air drag.It is also most important external force to be encountered when air drag is running car maximum, with work vehicle row
The increase of speed is sailed, air drag is increasingly becoming most important car resistance, when more than speed per hour 200km/h, air drag
Almost account for the 85% of all car resistances.
Windage is the vehicle resistance from air when driving, and for general air drag there are three types of form, first is that air-flow is hit
Resistance caused by vehicle frontal, just as one piece of plank is taken to go against the wind, suffered resistance is nearly all that air-flow shock is produced
Raw resistance.Second is frictional resistance, and air can generate frictional force with streaking as vehicle body, however can be travelled with general vehicle
For prestissimo, frictional resistance is small to can almost ignore.Third is then outer form-drag, in general, high vehicle speeds
When, outer form-drag is most important air drag source.As shown in Figure 1 and 2, the resistance caused by external form is from the true of vehicle rear
Dead zone, vacuum area is bigger, and resistance is bigger.In many car conour designs improve, only focus on the moulding of windward side mostly
Structure, and the structure for having ignored automobile tail is improved, however during galloping, the vacuum area of automobile tail is formed in vapour
The resistance of vehicle is tended to exceed from windward side resistance.
For general vehicle when advancing, the resistance of suffered wind is substantially from front, unless side wind speed is especially big.Not so not
It can have much impact to vehicle, 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, 60% oil consumption is for overcoming windage.Coefficient of air resistance,
Also known as air resistance coefficient is a significant coefficient for calculating air resistance of automobile, is to weigh an automobile to be influenced 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 vehicle in motion.The size of air resistance coefficient depends on the shape 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, windage
Coefficient is smaller, and therefore, most of body of a motor car all uses fairshaped design in existing design.However, with auto industry
