The current elastoplastic interface load-bearing contact model ignores the time-dependent changes of textured element Micro-Convex Peaks (MCP) base diameter, which is usually regarded as a certain constant value, and which is extremely inconsistent with the time-varying characteristics of MCP matrix diameter of actual MTMI, which leading to the deviation of load-bearing analytical values determined by the current contact model from actual data. A generalized Thermo-Elastic Hydrodynamic Lubrication (TEHL) contact load-bearing model with Interface Micro Texture (IMT) is proposed, and the contact area between all MCPs across the MTMI is represented by the equivalent scale factor parameter, and the shape distribution density function is modified to ensure that the MCP is solved integrally. A mathematical model of meshing Anti-Scuffing Load-Bearing Capacity (ASLBC) in a TEHL steady state is derived to reveal the correlation between contact stiffness and damping of meshing MTMI under alternating loads influence, which provides a theoretical basis and data reference for homogeneous Interface Enriched Lubrication (IEL) effect improvement and meshing ASLBC enhancement of contact IMT for the PRTS.
