OS0406 Multiscale Estimating Technique of the Friction Coefficient of a Rubber Sliding on Complex Surface Asperities

Abstract

Based on the Persson's mathematical model, we propose the procedure of estimating the friction coefficient for a rubber block sliding on a road surface with multiscale asperities. In our model, we create a new methodology of determining the wavenumber range for the calculation from the standpoint of elasticity limit of rubber. Comparing the estimated friction coefficient with that of experiment, we also discuss the some factors of the rubber friction due to hysteresis loss, adhesion and local temperature increase.
