چکیده
Friction loss in an internal combustion engine largely depends on elastohydrodynamic lubrication. The piston compression ring is a contributor to such parasitic losses the subsystem. complex elastodynamics of are responsible for transient and regime-altering film that affects lubrication liner contact conjunction. current paper will discuss radial, lateral deformation, axial twist, its effect profile subsequent tribological characteristics like pressure, friction, lubricant. A finite difference technique used solve issue elastodynamic by introducing elastodynamically influenced thickness into model. results show consideration predicts 23.53% reduction friction power stroke due compared rigid ring. improves lubricant oil flow element simulation von-Mises stress 0.414 N/mm2, maximum deformation 0.513 µm at core coating interface observed ring–ring groove contact. sustainability EHL this case ring–liner elastodynamics.

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 کاملStabilized Finite Elements for Elastohydrodynamic Lubrication Problems
In this work, we are mainly interested in modelling a particular lubrication regime known as Elastohydrodynamic (EHD). The pressure generated in the conjunction is high enough to induce a significant elastic deformation of the contacting bodies. Therefore a strong coupling between hydrodynamic and elastic effects is involved. A finite element full-system approach is used to model the lubricant ...
