In order to study the rolling behavior on rough surfaces, the rolling friction acting on a roller, which is rolling on model asperities, is measured preciously. The model asperities are cylindrical bars, which represent unidirectional asperities on a ground surface. It is clarified in our experiment that the rolling friction becomes small with the increase of the normal load acting on the roller, when the roller is pressed at the pressure close to the yield point. According to the assumption that the contact region between the roller and the cylindrical bar moves forward to generate the resisting moment, the above-mentioned rolling behavior can be explained qualitatively, moreover the reduction in the contact area is suggested. The reduction in the contact area is supported by the electrical contact resistance measurement. Thus, one aspect of the rolling contact mechanisms is confirmed.
