The contact between a cylindrical steel indenter and an elastomer with high adhesive properties has been investigated. Good agreement between computer simulation and experimental data was obtained for the indentation and detachment processes in the normal direction. The adhesive component of the friction force in the rolling-friction regime was determined by analyzing the relationship between the tangential component of the contact force and wheel displacement. The presence of adhesion was found to affect sliding friction, with the force being proportional to the contact area.
Normal and tangential contacts between a cylindrical steel indenter (wheel) and an elastomer possessing high adhesive properties have been investigated. Computer simulation of the indentation and detachment processes has been performed for the case of indentation in the normal direction, which demonstrated good agreement with experimental data. For the rolling-friction regime, the adhesive component of the friction force has been determined by analyzing the measured dependences of the tangential component of the contact force on wheel displacement. A case of sliding friction with blocked wheel rotation has been considered. In the presence of adhesion, the sliding-friction force is proportional to the contact area. In the absence of adhesion (the elastomer is completely coated with chalk dust), stick-slip friction is implemented. The frequency and amplitude of stick-slip transitions depend on the indentation depth in the elastomer.
