...M. Decote; N. Fillot; Y. Mahéo; G. E. Morales-Espejel Despite many researches in the past decades, starvation modeling of an elastohydrodynamic lubricated (EHL) contact is still an arduous task. The well-established Jackobson, Floberg, and Olsson (JFO) theory indeed shows jump discontinuities...

...He Liang; Zhihan Fan; Wenzhong Wang; Ziqiang Zhao Most of the rolling bearings work under starvation conditions. The quantitative measurement of the oil layer may provide a new perspective on the rolling bearing lubrication. In this research, the laser-induced fluorescence technique was utilized...

Morales-Espejel In the present work, we evaluate the effects of lubricant starvation on the film thickness of spinning large-size point contacts from an experimental standpoint...

...S. Li; A. Kolivand; A. Anisetti Utilizing a computational approach, this study quantifies the onset of lubrication starvation for line contacts of rough surfaces operating under typical ranges of automotive gearing applications. The response parameter is selected as the critical film thickness...

... coefficient simultaneously. The evolution patterns of the grease films with disc revolutions are affected by SRR, entrainment speed, and grease consistency. The severe starvation due to film decay at low shear and the film recovery at high shear has been recognized. The grease with low consistency...

...Surojit Poddar; N. Tandon This present article evaluates the state of starvation in a journal bearing using acoustic emission (AE) and vibration measurement techniques. A journal bearing requires a constant supply of oil in an adequate amount to develop a hydrodynamic film, thick enough to separate...

... (degree of starvation) and the layer variation amplitude is illustrated. Subsequently, using results for different load conditions, wavelengths, and degrees of starvation, it is shown that the response of the contact to such variations is determined by a nondimensional parameter, which represents...

...K. Stadler; N. Izumi; T. Morita; J. Sugimura; B. Piccigallo Reciprocating lubricated contacts sometimes suffer from oil starvation due to cavitation at the reversal of motion. However, the behavior of cavities is not well understood such that starvation can be theoretically predicted. In this study...

...P. Singh; R. K. Pandey; Y. Nath The main objective of this research is to analyze the variation of minimum film thickness in the inlet zone of roll-strip interface by incorporating starvation and viscous shear heating effects at high rolling speeds ( 5 – 20 m ∕ s ) , reduction ratios (0.05–0.20...
