| Abstract: | Based on the assumption of flexible tread and rigid carcass, longitudinal deformation of contact patch for longitudinal slip properties and longitudinal and lateral deformations of contact patch for combined longitudinal slip and cornering properties are analyzed in steady state conditions. Modelling mechanisms are described concerning longitudinal slip brush models and combined longitudinal slip and cornering brush models in steady state conditions when slipping occurs within contact patch. The following aspects are also discussed respectively: the variations of longitudinal shear force with braking force and driving force, the vector interrelation of total shear force of combined longitudinal slip and cornering properties versus its components respectively in longitudinal and lateral directions, and internal relations of combined longitudinal slip and cornering brush model with the longitudinal slip brush model and the cornering brush model. |
