method based ...
Periodic Solutions of Some Differential Equations that Show the Non-Linear Vibrations of the Mechanical Systems
(Universitatea "Dunarea de Jos" din Galați, 2009)
Many phenomenons of mechanical nature possess non-linear
vibrations, their mathematical forming operation leading to differential
equations or to systems of differential non-linear equations.
In this work it is shown ...
About the Vibrations of the Mechanical Systems with Non-Linear Damping
(Universitatea "Dunarea de Jos" din Galați, 2009)
This work will analyze the non-linear vibrations of the mechanical
systems, actually the ones with non-linear damping. If we consider
damping F( x,x ) x( k k x );k1,k2 R

Functional Aspects for Antiseismic double Sliding Isolation Systems
(Universitatea "Dunărea de Jos" din Galați, 2015)
In order to counteract the soil sudden movements as a result of seismic
actions, a disconnection between the primary components of a specific
structure was needed, so that the efforts can not be transmitted on ...
Principle of Elastomeric Supports as Antiseismic Isolation Systems
(Universitatea "Dunărea de Jos" din Galați, 2014)
Special systems have been designed to be mounted at building structures
acting against the effects of ground dynamic motions caused by
earthquakes. Such systems considered as isolators working on dynamic
regime are based ...
The Friction Force Dependence at Simple Pendulum Sliders by Relative Speed and Temperature of the Surface in Contact
(Universitatea "Dunărea de Jos" din Galați, 2014)
Some bridges located in areas of high seismic risk have the decks supported through simple pendulum what dissipates energy by dry friction. The friction force that occurs by motion of the two surfaces is dependent on both ...
