Abstract
The visualization of the rubber slip in the contact area during rolling-sliding friction was reviewed. The contact area between the rotating rubber wheel and the mating glass was observed simultaneously to understand how the sliding region and the adhesion region related to the -S characteristics during the rolling-sliding friction. Small markers with equal intervals were observed to measure the movement rates of the rubber surface in the contact area. As the results, the adhesion region and the sliding region in the rolling-sliding contact area were measured during sliding. The adhesion region, however, decreased to zero as the slip ratio attained to 15%. There was only the sliding region in the contact area at the slip ratio more than 15%.
