Short summary
A thermoelastic hydrodynamic lubrication (TEHL) model with interface micro-texture (IMT) evaluates load-bearing capacity. The model characterises the textured interface with micro-convex peaks (MCPs) by introducing an equivalent scale factor and an optimised distribution density function. A mathematical framework quantifies anti-scuffing load-bearing capacity (ASLBC) under steady-state TEHL, revealing coupled stiffness–damping in a micro-textured meshing interface (MTMI) under dynamic loading.
