Improving machine energy efficiency has led to the use of lower viscosity lubricants, and a
greater chance of mixed/boundary contact occurring. A new equation, derived from …

This paper proposes a method for detecting insufficient lubrication in rolling bearings, by
utilising a low cost MEMS ultrasonic microphone. We run a set of grease lubricated bearings …

Under severe conditions, solid contacts take place even when parts are lubricated. Precise
mathematical conditions are needed to describe the interior interface between fluid …

The performance of rectangular-rounded, elastomeric, hydraulic rod seals for reciprocating
motion is theoretically evaluated in terms of the mass leakage per cycle, frictional work and …

For transient mixed Elastohydrodynamic lubrication (EHL) problems, a novel solution is
required to predict friction loss and wear in sliding or rolling parts. However, existing …

The increasing requirement of high-power density (power throughput/weight) in modern day
machines lead to thin film lubrication condition in various machine components (rolling …

Metal conditioners (MC) are added to lubricants to enhance their friction and wear in friction
pairs, mainly in engines, gearboxes, and rolling bearings. Its growth in the Brazilian market …

This study investigates the effects of harmful bearing currents on the service life of rolling
bearings and introduces a model to predict service life as a function of surface roughness …

Synovial joints, such as the elbow, experience different lubrication regimes, ranging from
fluid film to boundary lubrication, depending on locomotion conditions. We explore the …

The increasing use of low-viscosity lubricants in order to reduce the friction in machine
elements such as rolling bearings is leading to increased operation in the mixed or …
