Numerical Analysis Method for Friction Characteristics of Tire-pavement under Wet Slip Condition

doi:10.3901/JME.2020.21.177

Abstract

Abstract: In order to study the friction characteristics of tire pavement under wet conditions, tread rubber and asphalt pavement are chosen the research objects. Three-dimensional rough pavement is established by virtue of the harmonic superposition method, and the “sealing” effect of water film is equivalent to “pseudo” hydrodynamic lubrication effect. For the contact pressure, hysteresis friction and water film bearing capacity under wet slip condition are obtained by ABAQUS and Fluent software, and the numerical analysis method for friction characteristics of tire-pavement friction coefficient under wet slip condition is established, which takes into account the rubber material, contact pressure, sliding speed, road profile and water film. From comparing the numerical results with published experimental results, the results show that this analysis method is practical and reasonable. Based on that, the effects of sliding speeds, contact pressures and road profiles on friction characteristics were investigated. The research provides theoretical basis of design and optimization for the wet-skid resistance of tires and roads.
