ABSTRACT The operational reliability of thermal control circulation pumps is significantly restricted by the multi‐physics coupled environment. To reveal the vibration transmission mechanisms and dynamic response characteristics under multi‐field coupled excitations, a multi‐DOF coupled dynamic representation of the overall system, incorporating the ...

On the Reynolds lubrication equation [PDF]
Let Ω be a bounded open set in R 2 with “smooth” boundary ∂Ω. Ω is the region where two solid bodies are in contact. These two solids are moving and the average of their velocities is denoted by V=(V 1 ,V 2 ).

Numerical Simulation of the Lubricant-Solid Interface Using the Multigrid Method
Solid asperity interactions are common and inevitable under severe loading conditions for any lubricated contact. Heavy-duty machine components (gears, bearings, etc.) generally operate under Mixed Lubrication (ML), where uneven surface features contact ...

Multi-scale analysis of the roughness effect on lubricated rough contact [PDF]
Determining friction is as equally essential as determining the film thickness in the lubricated contact, and is an important research subject. Indeed, reduction of friction in the automotive industry is important for both the minimization of fuel ...

UHMWPE provides interfacial lubrication, improving tribological performance of PEEK‐based sliding bearing bushings. ABSTRACT Ultra‐high molecular weight polyethylene (UHMWPE) was incorporated into a PEEK‐based hybrid material as a lubrication additive to improve the friction and wear performance of the composite due to its superior lubricity ...
