Elastohydrodynamic Grease Lubrication Theory and Numerical Solution in Line Contacts
In this paper, film thickness and pressure distribution of EHL in line contacts for four kinds of greases and one type of oil are calculated under a series of rolling velocities by wing an inverse solution method. The Herschel-Bulkley model is wed for the rheological characteristics of the grease. Based on the theoretical analysis and numerical calculation, the following influences on film thic...
متن کاملElastohydrodynamic lubrication of faults
The heat flow paradox provides evidence that a dynamic weakening mechanism may be important in understanding fault friction and rupture. We present here a specific model for dynamic velocity weakening that uses the mechanics of well-studied industrial bearings to explain fault zone processes. An elevated fluid pressure is generated in a thin film of viscous fluid that is sheared between nearly ...

متن کاملDiscussion: “Temperature of Food and Drink Intake Matters” (Wong, K. V., 2016, ASME J. Energy Resour. Technol., 138(5), p. 054701)
Wong’s article seeks to model the energy balance of humans inclusive of both sensible and oxidative energy content of food with the objective of finding means to modify the human energy balance and reduce obesity [1]. The author proposes that the temperature at which foods and beverages are consumed can make a significant contribution to whole body energy balance, and the temperature of foodstu...
متن کاملComparison of fatigue model results for rough surface elastohydrodynamic lubrication
The paper compares the results of applying different fatigue failure models to surfaces that experience elastohydrodynamic lubrication (EHL) and have surface roughness features which are large compared with the equivalent smooth surface film thickness. The surface profiles used for the comparisons reported are taken from test gear surfaces used in an FZG gear test. The surface has a roughness o...
