This article is focused on the comparison between experimental and numerical friction
forces obtained for a typical hydraulic 'U'rod seal. The numerical results are obtained by the …

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 …

Based on the sealing mechanism of the reciprocating seal, the inverse-hydrodynamic-
lubrication (IHL) method was adopted in this study to solve the Reynolds equation, and a …

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 …

A mixed‐lubrication numerical model for hydraulic seals by the inverse‐hydrodynamic‐
lubrication method is presented in this paper for the first time. The hydrodynamic effect on …

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

Current trends concerning hydraulic cylinder sealing systems are aimed at decreasing
energy consumption which can be materialized by minimizing leaks and reducing friction …

This study investigates how operating conditions such as ambient temperature and sealing
pressure affect sealing performance for a typical U-cup seal. The developed analysis …

The reliability of the reciprocating seal is the key to ensuring the regular operation of the
entire hydraulic system. Since friction in the sealing area under reciprocating conditions and …
