OS0202 Experimental Evaluation of Hysteresis Friction of a Sliding Rubber on a Road with Multiscale Asperities
Details
In the Persson's contact mechanics theory, the friction model of a sliding rubber has been proposed, accounting for the surface property on multiscale asperities; the friction coefficient which is equivalent to hysteresis loss is mathematically derived by the rubber's viscoelasticity and the surface roughness power spectrum. In this study, we conduct friction tests under two types of normal loads. We compare the friction coefficients calculated from the Persson's theory with those of experiments so that the hysteresis friction is discussed as a factor of the friction mechanism based on the sliding velocity dependence of the friction coefficients.
