Structured Surfaces used for Improving Tribological Behaviour for the Piston – Ring Cylinder – Liner Friction Couples in Internal Combustion Engines
(Universitatea "Dunărea de Jos" din Galaţi, 2007)Structured surfaces means the achievement of a rate, or controlled micro-geometry for one or both friction surfaces. These surface profiles are used to guarantee lubrication functions of transport, hoarding and spread of ... -
A Study on the Prediction of Stability Behaviour for Flexible Rotor in Journal Bearings
(Universitatea "Dunărea de Jos" din Galaţi, 2007)The influence of the labyrinth seals on the dynamic behaviour of a flexible rotor in journal bearings is investigated. In particular a code which makes possible the determination of the stiffness and damping coefficients ... -
The Level of Confidence for a Ship Hull Girder
(Universitatea "Dunărea de Jos" din Galaţi, 2007)Structural estimation consists in a set of activities done to certificate security and reliability of an existing ship for its residual service life. Depending on ship’s type and damages, there are alternatively evaluation ... -
The Resulted Roughness at Turning of some Non-Metallic Materials and Correlation with Durability of Machine Cut Surfaces
(Universitatea "Dunărea de Jos" din Galaţi, 2007)In this paper there are studied the results obtained at graphite and polyvinyl chloride turning. Such pieces are used like loose parts or in subassemblies. The final roughness of such pieces after processing and the influence ... -
Wear Prediction of Hip Endoprostheses
(2007)The total hip prostheses can be considered as medical-mechanical devices with established failure. The large domain of common activities induces a wide spectrum of loadings in contact prosthetic parts. The contact conditions ...
