Let’s learn the basis of tire slip in this video. A good understanding of this topic is imperative before proceeding to the other vehicle dynamics videos.In (automotive) vehicle dynamics, slip is the relative motion between a tire and the road surface it is moving on.
This slip can be generated either by the tire’s rotational speed being greater or less than the free-rolling speed (usually described as percent slip), or by the tire’s plane of rotation being at an angle to its direction of motion (referred to as slip angle). Watch the video from Lesics:
Friction can create heat and smoke can often be seen coming from the tyres of racing cars. The friction between the road surface and the tyre causes the tread in the tyre to wear down.
In rail vehicle dynamics, this overall slip of the wheel relative to the rail is called creepage. It is distinguished from the local sliding velocity of surface particles of wheel and rail, which is called micro-slip.
