WebThe theory of rubber friction recognizes three major friction forces: adhesion force, bulk deformations (hysteresis), and cohesion losses due to the wearing of rubber [4]. The … Webfriction against PDMS was found to be greater than that of the hydrocarbon monolayer. The values of the friction forces do, however, follow the same general trend as the … admin processing case status WebOn the basis of rubber viscoelasticity, the tribological behavior for rubber/DLC composites was explored. The friction mainly originated from two parts:adhesion between grinding ball and composites, hysteresis effect of rubber. The viscoelasticity of rubber caused the variable size and shape of friction contact area. WebUltimately, Kummer’s theory of tire friction is based on two sources or mechanisms of energy dissipation that are responsible for skid resistance, or what is referred to as tire “friction”. These are adhesion and hysteresis. It is argued here that adhesion plays no role in tire friction. It is also argued that hysteresis is related admin processes and procedures WebJan 1, 1993 · Melvina Leolukman and, Seong H. Kim.
