Numerical analysis of the influence of film thickness and properties on the stress state of thin film-coated piston rings under contact loads
In this work, a series of finite element analyses was conducted to analyze the stresses in thin film-coated piston rings under contact loads. The actual normal and tangential pressure observed during a complete four-stroke ...
Tribological performance of textured surfaces in the piston ring/liner contact using the elrod-adams model
(Instituto Balseiro - Centro Atómico BarilocheBariloche, 2014-09-23)
The possibility of improving the performance of lubricated surfaces through surface texturing
has been a topic of intense research in the latest years. Considerable efforts in both experimental
and numerical works have ...
Failure analysis of a damaged direct injection diesel engine piston
(Springer New York LLC, 2017-08-24)
This work deals with the piston failures found in diesel engines functioning in light trucks. The failure was a hole inside the bowl located at the top of the piston, which is the combustion chamber of the engine. This ...
Moving textures: simulation of a ring sliding on a textured liner
(ElsevierAmsterdam, 2014-04)
Numerical simulations of the ring/liner contact in which the liner exhibits a periodic texture (pockets)
are reported. The mass-conservative Elrod–Adams model is used to treat cavitation, and the dynamics
of the ring is ...
Surface Texturing in Machine Elements − A Critical Discussion for Rolling and Sliding Contacts
(Wiley-VCH Verlag, 2019)
Surface texturing has gained great attention in the tribological community since precisely defined surface features can help to reduce friction and/or wear irrespective of the acting lubrication regime. The ability to ...
Modelling the hydrodynamic support of cylinder bore and piston rings with laser textured surfaces
(Netherlands, 2013)
An one-dimensional computer model was used to simulated surface texture effects on engine cylinder bore, top and oil control rings. Steady state, reciprocating tests and engine conditions were considered. For the engine ...
