چکیده
Abstract A numerical method is proposed to evaluate the effect of non‐Gaussian roughness on point contact elastohydrodynamic lubrication (EHL). mixed EHL model contact, considering roughness, developed. The oil film pressure in was controlled by Reynolds equation average flow, and asperity obtained rough surface micro‐contact model. influence parameters distribution, thickness profile ratio load (asperity ratio) are investigated based results show that increases as root mean square (RMS) increases, skewness kurtosis. also with RMS skewness, but not sensitive

Comparison 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...
متن کاملOn the linear finite element analysis of fully-coupled point contact elastohydrodynamic lubrication problems
The fully coupled approach for the solution of elastohydrodynamic lubrication (EHL) point contact problems requires the numerical solution of the elasticity problem on a large 3D domain. A sufficiently fine computational mesh is required to obtain the elastic deformation solution to the necessary accuracy, and hence a sufficiently accurate EHL point contact solution. This paper discusses the ac...

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 کاملAdaptive high-order Discontinuous Galerkin solution of elastohydrodynamic lubrication point contact problems
This paper describes an adaptive implementation of a high order Discontinuous Galerkin (DG) method for the solution of elastohydrodynamic lubrication (EHL) point contact problems. These problems arise when modelling the thin lubricating film between contacts which are under sufficiently high pressure that the elastic deformation of the contacting elements cannot be neglected. The governing equa...
