The Minimum Film Thickness in Line Contacts During Reversal of Entrainment
Journal of Tribology, 1993In contacts, such as cams, non-involute gears and shaft seals, where the direction of entrainment reverses during the operating cycle, the minimum film thickness is typically found just after the reversal. This paper shows that this minimum film thickness is determined by the rate of change of the entraining velocity and by the fluid and surface ...

Full EHL line contact simulations for smooth surfaces are carried out under fully flooded condition to obtain central and minimum film thickness equations pertaining to lubricants with linear piezoviscous response. The present analysis is based upon the assumptions of isothermal condition and Newtonian fluid model.

In the first paper of this series, a new formula for central film thickness of slender contacts has been proposed. In this paper, interferometry measurement of the film thickness in slender elliptic contacts is performed for comparison with film thickness distribution of EHL simulation.

On the optimal control of minimum film thickness
Journal of Optimization Theory and Applications, 1990The present paper is concerned with the study of controlling the motion of a bearing so that the thin film of lubricant separating it from its container will have the largest possible thickness. Explicit equations are derived, and the control problem is solved explicitly in some simple cases.

Tunnelling in thick-film (cermet) resistors and the minimum of resistance
Il Nuovo Cimento D, 1983The electrical transport in thick-film resistors (TFRs) is actually an active field of investigation on both theoretical and experimental bases. Previously it has been shown that tunnelling of electrons between neighbouring grains could explain a large spectrum of experimental findings and it has been proposed that the minimum of resistance of TFRs is ...

Recent numerical results have indicated that the relationship between the film thickness and the speed may not always follow the simple power law, especially under severe conditions. This paper is aimed at obtaining experimental results at high contact stresses and low speeds to study the thin film behavior.

Experimental Investigation of the Minimum Oil-Film Thickness in Spur Gears
Journal of Basic Engineering, 1963As a pair of gears is loaded, the minimum oil-film thickness between the gear teeth decreases and can approach a magnitude equal to the magnitude of the surface roughness. Metal-to-metal contact then occurs between the microscopic peaks on both mating teeth surfaces.
