Abstract: During the wear process of surfaces in sliding friction, there is a running-in period during which the topography of surfaces changes with time before reaching the steady wear regime. In the steady wear regime, the statistical ...

Abstract: This paper presents a general formulation of the Reynolds equation for gas and liquid lubricants, including cavitation. A finite element solution of this equation is also given. The model is compared to those obtained in ...

Abstract: This paper presents a novel method to compute the lubricant pressure distribution between a rough and a smooth surface in relative motion. The originality of this method is to combine a deterministic approach for the large ...

Abstract: An experimental test rig has been used to analyze the lift-off condition of a squeeze film thrust bearing. It is composed of a vibrating flat plate linked to a piezo-actuator, a cylindrical mass, and two displacement ...

Abstract: Inward pumping spiral groove seals are used in many applications, such as transmission gearboxes or electric vehicles, as they can provide zero leakage and very low operating friction. The spiral grooves are connected to ...

Abstract: Segmented bi-Gaussian stratified elastic asperity contact model of Leefe (1998, “‘Bi-Gaussian’ Representation of Worn Surface Topography in Elastic Contact Problems,” Tribol. Ser., 34, pp. 281–290), which suits for worn ...
