Key Points

  • The aim is to explore how a viscoelastic coating affects lubrication between an elastic ball and a rigid surface.
  • Utilized a one-dimensional Kelvin model to represent the viscoelastic solid properties.
  • Investigated pressure dynamics within the lubricating layer influenced by the viscoelastic coating.
  • Assessed the impact of coating thickness on lubrication effectiveness.
  • Identified significant variations in pressure within the lubricant layer based on viscoelastic properties.
  • Found that the thickness of the lubricant layer is affected by the viscoelastic characteristics of the coating.

Abstract

The problem of rolling an elastic ball on the surface of a viscoelastic layer in the presence of a thin layer of lubricant separating them is considered. The viscoelastic layer is located on a rigid base. The one-dimensional Kelvin model of a viscoelastic solid is used as a rheological model of the viscoelastic layer. The influence of viscoelastic properties of the coating on the pressure in the lubricating layer and its thickness was investigated.
