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 ...
A Comparation of Standardized Methods for Lubrication Failure Determination
(Universitatea "Dunărea de Jos" din Galaţi, 2007)
Lubricants are used to prevent wear between moving parts and to resist to high pressure between them. There are standardized testing methods that determinate the wear of the contact pair pieces and the pressure that leads ...
Durabilyty of Friction Pairs With Functionality in Abrasive Randomly Particles
(Universitatea "Dunărea de Jos" din Galaţi, 2007)
It is shown that the abrasive particles, which penetrate in the convergent joint of friction pairs, can damage the superficial layer of surfaces. The wear caused by individual particle depends on having both a satisfactory ...
Neural Networks Based Study of Friction Coefficient Variation in Sliding Bearings
(Universitatea "Dunărea de Jos" din Galaţi, 2007)
The paper presents the possibility of using the neural networks approach for the analysis of friction coefficient evolution in case of sliding bearings.
Several non-metallic bearing materials are investigated, both with ...
