Multi-lip reciprocating seals are extensively used in the subject of engineering equipment. However, current research on tribology mainly focused focuses numerical analysis single-lip seals. In order to study sealing performance multi-lip seals, this paper takes double-acting seal (DAS) as object, and establishes a mixed elastohydrodynamic lubrication (M-EHL) simulation model from perspective s...

Abstract Lubricated contact processes are studied using classical molecular dynamics simulations for determining the entire range of Stribeck curve. Therefore, lateral movement two solid bodies at different gap height studied. In each simulation, a rigid asperity is moved constant above flat iron surface in lubricating fluid. Both methane and decane considered as lubricants. The three main lubr...

A mixed lubrication model is developed to investigate the lubrication of coupled journalthrust-bearing systems. The governing equations are mapped into a computational domain with a conformal mapping technique developed in a previous study by Wang et al. (2002). In order to study the influence of the boundary conditions on the performance of the bearing system, either the Reynolds boundary cond...

Ensuring effective lubrication between sliding surfaces is one of the challenges in the field of tribology. In addition to the conventional parameters like speed, load, contact geometry and material parameters, the surface texture also influences the coefficient of friction. In the present investigation, the effect of surface texture on coefficient of friction under boundary lubricated conditio...

In this study, in order to investigate the lubrication characteristics of the sliding surface of the vane in a rotary compressor, numerical analysis for mixed lubrication has been developed. In this analysis, the modified Reynolds equation and the elastic contact equation, considering the surface roughness, are solved as a coupled problem. Using this analysis, the lubrication characteristics of...
