Abstract
AbstractIn this study, based on the flow equation of a ferromagnetic fluid for a thin layer, the continuity equation, and the equation describing the profile of the molten contour of the guide coated with a low-melting metal alloy, considering the mechanical energy dissipation rate, the accurate asymptotic self-similar solution has been found for the zero (without considering the melting) and first (considering the melting) approximation for wedge-shaped sliding support with nonstandard support profile of the slider and the low-melting metal coating of the guide surface, considering the rheology of the lubricant and the melt having ferromagnetic properties in the laminar flow. Analytical dependences have been obtained for the molten surface profile of the guide coating, as well as the field of velocities and pressures for zero and first approximations. Also, the basic performance characteristics of the friction pair under consideration, the bearing capacity, and the friction force have been determined. The impact of the parameters conditioned by the coating melt, a support profile adapted to friction conditions, and a parameter characterizing the rheological properties of the lubricant on the bearing capacity and friction force has been estimated.KeywordsHydrodynamicsSliding support (sliderGuide)Ferromagnetic incompressible liquid lubricantMolten guide surfaceNonstandard slider support surfaceAccurate self-similar solutionAsymptotic solution
