Mechanistic Analysis of Textured IEL and Meshing ASLBC Synergy in Heavy Loads: Characterizing Predefined Micro-Element Configurations

Friction contact regulation has been widely acknowledged, yet research on mi-cro-textured meshing interfaces appears to have reached an impasse. Conventional wisdom holds that the similarity of micro-element configurations is the key factor con-tributing to textured interface issues. The traditional perception is transcended, and a novel method for presetting the optimal parameters of gradientized mi-cro-textured interface elements is proposed. The study has analyzed the Interface En-riched Lubrication (IEL) performance and meshing Anti-Scuffing Load-Bearing Ca-pacity (ASLBC) of periodic symmetrical and continuously gradient micro-elements. By actively regulating IEL behavior through geometric constraint effects, dynamic mi-cro-cavity lubrication storage units are formed, thereby extending the retention time of medium film layers. The textured edges induce micro-vortices, delaying scuffing fail-ures induced by load-bearing. Validation analyses demonstrate that optimal mi-cro-element configurations can distribute contact stress to achieve stress homogeniza-tion, with the maxi-mum contact stress reduced by 21%. The localized hydrodynamic effect of micro-textured elements increases interfacial meshing stiffness by 5.32% while decreasing friction torque by 27.3%. This investigation reveals a synergistic mechanism between IEL performance and meshing ASLBC under heavy loads condi-tions. The findings confirm that gradient-based micro-textured element configuration presetting offers an effective solution to reconcile the inherent trade-off between lu-brication and load-bearing performance in heavy loads applications.
