4 Μαρ 2017 · The forces that a moving vehicle must overcome are the tire rolling resistance, the driveline friction, elevation, vehicle acceleration changes, and also aerodynamics. Let us assume that the vehicle moves along a flat surface at a constant speed and the external forces are limited to the tire friction and to the aerodynamic drag.
20 Οκτ 2022 · The field of automotive aerodynamics involves examining the airflow around a vehicle. The goal is to diminish drag and wind noise and avoid unintended lift forces contributing to aerodynamic instability, particularly at high speeds.
13 Ιουν 2024 · How air flows under or over your modified car is critical for both its performance and your safety. We investigate the key principles in our car aerodynamics guide. ‘Aero’ is a wonderfully vague catch-all phrase that the car community loves to throw around when talking about a certain genre of modification, but what does it actually mean?
Friction: The second most important fact you'll face. Because the dragster has parts moving against one another, friction is created. You can help reduce it by making sure the axles are free to rotate, and that the wheels and tires are not rubbing on the car body.
21 Νοε 2022 · Friction drag happens because it takes energy to make layers of air slide past one another. The rougher or more obstructive the object, the more turbulent the air flow becomes, the greater the friction between the layers, and the greater the drag.
Aerodynamic drag, sometimes called wind resistance, is an effect which a vehicle must overcome more and more as speed increases. Drag is a form of friction, though some of the air's effect on the vehicle is due to a low pressure zone behind the vehicle, and a high pressure zone in front.
Stock Car Aero Push. A speeding stock car pierces the air as it travels. Air swooshes over the top of the car and is deflected by the spoiler attached to the rear deck. If another car trails immediately behind, nose to tail, it continuously enters airspace affected by the car in front.
