摘要

The study addresses the influences of frictional properties between tire tread and pavement. A semi-empirical model of the shear force properties of truck tires is used to illustrate the influences of tread groove depth, roadway skid number, and the mean texture depth of the pavement on the lateral and longitudinal forces generated by truck tires. An existing tire model is described; additions to the model providing an enhanced representation of frictional properties are also discussed. Empirical formulas based on information published in the literature are used to represent the frictional characteristics of 'poor wet roads.' The influences of vertical load, forward velocity, slip angle, and longitudinal slip are included in the analyses.
