Hydraulic seal, generally made up of elastomers, is used in hydraulic systems to prevent the
leakage and facilitate the efficient transmission of fluid power into mechanical power. Most of …

Hydraulic actuators are an important executive component of modern aircraft and are
typically characterized by a reciprocating sealing form. Sealing failure affects the …

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 …

In the hydraulic system, investigation of seal failure is very important for reliable operation.
The U-cup seal of thermosetting amorphous polyurethane material was tested to analyze the …

By analyzing the principle of pressure balance in the sealing area, a more stable and faster
convergence fluid–solid coupling numerical algorithm is proposed. The overall flexibility …

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 …

Reciprocating seals are widely used in general industrial machines and are designed to
endure rigorous working conditions. Among the harshest challenges, the wide temperature …

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 …
