In this paper a numerical approach is applied to analyse the influence of wear on the
lubrication and sealing mechanism of radial lip seals. A three-dimensional multi-scale …

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 …

The macroscale simulation methods are commonly used to study wear of rotary lip seals.
These methods oftentimes do not address effects of microscopic interfaces, which, according …

Researches on the reciprocating seals lubrication under elastic-hydrodynamic lubrication
(EHL) are mature, and leakage of failure criterion has been described with Couette flow for …

Within the last years, the amount of fluorelastomer (FKM) seals are increasing dramatically
in industrial applications such as gearboxes due to its outstanding characteristics and …

The effects of the textured shaft on the wear and sealing performance of rotary lip seals have
recently attracted considerable attention. This paper presents a numerical method for …

Rotary lip seal is widely used in aircraft and its performance affects the safety of the aircraft.
Hence, it is necessary to estimate useful lifetime and reliability of the seal. Degradation of …

A two-dimensional elastohydrodynamic numerical analysis is conducted for a rotary lip seal
with a textured shaft by coupling flow, deformation and contact equations. In this analysis, an …

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 …

Radial oil seals prevent leakage in mechanical systems where a rotary shaft passes a
housing interface. Hydrodynamic features are added to augment the self-induced back …
