Abstract
Tire—road surface contact is a complex combination of stresses and deformations that depend on tire and road factors, such as vehicle speed, weight, tire material and type, tire pressure inflation, camber and texture of the surface layer. In this paper, the problem of the tire-pavement contact is studied using a realistic description in normal section and corner. Mechanical field is validated with a press system under different inflation pressures and loads. The model requires precise tire geometry and an equivalent Young’s modulus. For this purpose, an optical method based on a photogrammetry method provided a 3D field of displacement. The estimation of the equivalent Young’s modulus is also proposed as a function of the inflation pressure resulting from the press load tests. Finally, a comparison is made between the measured footprint of the tire, the result of the semi-analytical calculation as well as the effect of tire inclination (corner/turn) on the distribution of surface stresses that is demonstrated.
