...Yaxin Liu; Lijie Ma; Qigao Feng; Guiling Hu; Leyang Li; Minghua Pang Purpose This study aims to reveal the impact of external vibration and frictional surface roughness on the friction-reduction of granular flow lubrication, to further enhance the lubricating effect of granular media...

...Lijie Ma; Xinhui Mao; Chenrui Li; Yu Zhang; Fengnan Li; Minghua Pang; Qigao Feng Purpose The purpose of this study is to reveal the friction reduction performance and mechanism of granular flow lubrication during the milling of difficult-to-machining materials and provide a high-performance...

... In this paper, a plane shear cell under granular lubrication is established by the discrete element method to study the flow constitutive relation and its mechanical mechanism of the hard granular lubricants. Findings Research results show that the flow regimes in granular flow lubrication strongly rely...

...Fanjing Meng; Kun Liu Purpose Granular flow lubrication is developed in recent years as a new lubrication method which can be used in extreme environments, while the stick-slip mechanisms of granular flow lubrication are an urgent obstacle remains unsolved in fully establishing the granular flow...
