| Abstract |
A study has been made of asperity interaction of unlubricated steel/rubber sliding pair.
The aim is to study the effect of the internal friction (hysteresis) of rubber on the friction force. In
the two-dimensional finite element analysis, asperities are modeled by cylinders and both the
interfacial adhesion and the friction at steel-rubber interface are neglected. Rate-dependent material
behavior of rubber is described, as a first approximation, by a three-parameter Zener-model. It is
found that the viscoelastic properties of rubber have a strong influence on the hysteresis component
of friction. Distribution of energy loss generated over a cycle of contact in the rubber asperity is
also studied. It is concluded that the energy dissipation is most intensive at a certain depth below the
rubber surface. |
