To provide a rubber friction test method and a rubber friction test device for appropriately evaluating frictional abrasion characteristics of a rubber test piece by obtaining the contact surface shape of the rubber test piece and calculating distortion distribution in the contact surface.
A rubber friction test method includes: a pattern formation process of forming a pattern 13 for image analysis on the outer peripheral surface 11 of a doughnut-like rubber test piece 1; a friction test process of rotating the rubber test piece 1 and a rotary drum 2 the cylindrical part 21 of which is formed of a transparent material while bringing the outer peripheral surface 11 of the rubber test piece 1 into contact with the rotary drum 2; an image acquisition process of photographing the outer peripheral surface 11 through the cylindrical part 21 simultaneously with the friction test process to acquire an outer peripheral surface image 11P; and an evaluation process of evaluating frictional abrasion characteristics of the rubber test piece 1 by obtaining the contact surface shape of the rubber test piece 1 from the acquired outer peripheral surface image 11P and calculating distortion distribution in the contact surface of the rubber test piece 1 on the basis of the pattern 13 for image analysis included in the outer peripheral surface image 11P.
