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).
Slip ratio is a means of calculating and expressing the slipping behavior of the wheel of an automobile.It is of fundamental importance in the field of vehicle dynamics, as it allows to understand the relationship between the deformation of the tire and the longitudinal forces (i.e. the forces responsible for forward acceleration and braking) acting upon it.
These coefficients are then used to generate equations showing how much force is generated for a given vertical load on the tire, camber angle and slip angle. [ 5 ] The Pacejka tire models are widely used in professional vehicle dynamics simulations, and racing car games, as they are reasonably accurate, easy to program, and solve quickly.
Stiffness is the extent to which an object resists deformation in response to an applied force. [ 1 ] The complementary concept is flexibility or pliability: the more flexible an object is, the less stiff it is.
Unless these sections have a longitudinal grade of at least 0.4–0.5%, the drainage gradient (resultant to crossfall and longitudinal grade) will be lower than 0.5% so water will not run off the road surface. Storm drains may be installed at regular intervals and modern paving materials are designed to provide high friction in most conditions.
