Description
Summary:The dependence of the contact characteristics and sliding friction coefficient on the density of the arrangement of contact spots is studied. To this end, the periodic contact problem of a system of asperities sliding on a viscoelastic base is considered. The main mechanism of the mutual effect of contact spots in the model in question manifests itself in the incomplete restoration of deformation on the free surface, with fairly dense arrangement of spots due to the imperfect elasticity of the base. The dependence is obtained of the friction coefficient on the spacing between asperities at various levels of effective loads and sliding velocities.
