Because of the fluid viscous shear and the asperity contact friction, a temperature rise will
occur in the sealing zone, which may cause rupturing of lubrication films or wear failure of …

The surface roughness of friction pairs plays a significant role in the formation of
hydrodynamic fluid film between rod-seal interface. To investigate the influence of rod …

A thermo-elastohydrodynamic lubrication model of a typical VL combined reciprocating rod
seal is established to analyze thermal-viscous effects on the reciprocating rod sealing …

Nonconvergence is a frequent problem for mixed lubrication modeling of reciprocating
seals, which couples a finite element analysis (FEA) commercial software with the fluid …

The oil film generation of a U-cup rod seal and the oil film thickness on the rod after
outstroke were analyzed analytically, numerically, and experimentally. The analyzed sealing …

The topography significantly affects the leakage prevention of the sealing surface. However,
the topography effect on sealing performance is not yet fully understood. The leakage …

A key factor influencing the friction of rod seals is a thin oil film, which is dragged into the
sealing gap at outstroke and instroke. Accurate determination of oil film thickness in the …

The work presented in this paper describes a new approach to calculate the film profile,
friction, and fluid transport of a reciprocating U-cup seal used in a hydraulic piston pump. An …

Multi-lip reciprocating seals are extensively used in the subject of engineering equipment.
However, the current research on the tribology of reciprocating seals mainly focused focuses …

Solid mechanics and rough thermoelastohydrodynamics of hydraulic, rectangular-rounded,
reciprocating seals with hydrodynamic, asperity, deformation and van-der-Waals stresses …
