Analysis of Two-Layered Journal Bearing Lubricated with Ferrofluid
The present study investigates the load capacity and friction coefficient for a two-layered journal bearing lubricated with ferrofluid. A modified Reynolds equation for a two-layered ferrofluid is derived using displaced infinitely long wire magnetic ...

CYLINDRICAL ROLLER BEARING LUBRICATION REGIMES ANALYSIS AT LOW SPEED AND PURE RADIAL LOAD
In this article, we describe a method of the roller bearing lubrication regime prediction. It uses a mathematical model of the bearing based on the standard ISO/TS 16281 to obtain the external load distribution over the rolling elements.

Study on mixed lubrication characteristics of piston/cylinder interface of variable length
Aiming at the lubrication problem of piston/cylinder interface of variable length, a two-dimensional mixed lubrication model was established. This model considers the adaptive eccentricity and the force balance of the piston.

DYNAMIC REYNOLDS EQUATION FOR MICROPOLAR FLUID LUBRICATION OF POROUS SLIDER BEARINGS
182 ABSTRACT In this paper an attempt has been made to study the rheological effects of micropolar fluid lubricants on the steady state and dynamic behavior of porous slider bearings by con- sidering the squeezing action. The general modified Rey- nolds-type equation of porous sliding-squeezing surfaces with micropolar fluids is derived for the ...
