Abstract
Summary. This paper presents a theoretical investigation on the decrease in grip coefficient of a car due to the car...
Highlights
The tire characteristics influence strongly the performance of the car, including stability, maneuverability, and safety and so on [1 - 5, 12, 14]
It is known that change of the vertical load and inflation pressure in the tire causes a variation of some tire characteristics, such as the grip coefficient in longitudinal and lateral directions, mileage of the tire and so on [2, 3, 5, 7, 8, 12, 13]
The car grip coefficients in longitudinal φаx and in lateral directionφаy were evaluated as φ ax where Fφxi, Fφyi are the grip forces of every tire in the respective direction; Ga – car gravity force
Summary
The tire characteristics influence strongly the performance of the car, including stability, maneuverability, and safety and so on [1 - 5, 12, 14]. It is known that change of the vertical load and inflation pressure in the tire causes a variation of some tire characteristics, such as the grip coefficient in longitudinal and lateral directions, mileage of the tire and so on [2, 3, 5, 7, 8, 12, 13]. Variation of the grip coefficient is studied for the car tires, and for the tires of semitrailers [10, 11] and agricultural tractors [9]. Changing of the mass distribution between front and rear axles influences the grip, the slip of traction wheels and on tractor efficiency [9]
