The Impact of Occupational Noise on the Workers. Romanian and EU Legislation
(Universitatea "Dunărea de Jos" din Galați, 2007)
Noise is most obviously a problem in industries such as manufacturing,
mining and construction but it can also be an issue in a wide range of other
working environments like energy, transports, call centers, schools,
orchestra ...
The Dynamics of the Rigid Body with Passive Hydraulics Linkages
(Universitatea "Dunărea d Jos" din Galați, 2007)
The paper refers to the case of the rigid body subject to linkages
materialised through linear hydraulics engines. We will settle the
mathematic model of the rigid and will determine its kinetic and dynamic
characteristics. ...
Dynamic Model for Hydraulic Dissipaters
(Universitatea "Dunărea de Jos" din Galați, 2008)
The paper deals with the problem of energy hydraulic dissipaters used as
dissipative links for mechanical structures subjected to earthquakes,
shocks and vibrations. The authors propose a mathematical model of a
hydraulic ...
Working Characteristics of the Special Isolation Devices Against Vibratory Actions
(Universitatea "Dunărea de Jos" din Galați, 2007)
The actual researches for finding optimal antiseismic protection solutions are
straightening to the few areas of activity: the first area of research is the base
isolation of buildings or theirs parts, against the ...
Numerical Simulations of the Special Isolation Devices Against Vibratory Actions
(Universitatea "Dunărea de Jos" din Galați, 2007)
In this paper the author use the physical and mathematical models for the
antiseismic and antivibrational elastic systems and describe the dynamic behaviour
of this systems, for the few types of the vital equipment - ...
Acoustic Absorption Coefficient Variationof Sound Absorbing Structures and Materials
(Universitatea "Dunărea de Jos" din Galați, 2008)
The task of this work is the acoustic absorption coefficient variation
study of sound absorbing structures and materials. Three construction
equipments have been considered according to their different cabin
design. ...
The Dynamic Modelling of the Mechanical Systems. Calculus of the Equivalent Mass and Equivalent Mass Inertia
(Universitatea "Dunărea de Jos" din Galați, 2007)
This study presents the phases and the final result of the physical and
mathematical models' elaboration of mechanical systems with elastical and
rigid elements taking into consideration the equivalent mass and inertia.
The ...
The Impact of the Technological Equipment Vibration on the Environment
(Universitatea "Dunărea de Jos" din Galați, 2007)
The shocks & vibrations generated by the operation of such tools, are
conveyed to the foundation environment affecting both the near – by
building safety and the comfort of the unit personnel and of the
surrounding ...
The Dinamic Response Analysis of the Viaduct Supported on Anti Seismic Systems with Selective Links as Viscoelastic and Dry Friction Type
(Universitatea "Dunărea de Jos" din Galați, 2013-10-01)
This paper analyzes, on the theoretical level, the dynamic response of a
viaduct section, dynamically isolated by systems with a selective type of
links with viscoelastic and with dry friction. Evaluation of kinematic
...
Nonlinear Approaches Regarding Mechanical and Thermal Behaviour of Visco-Elastic Vibration on Isolators
(Un, 2013-10-01)
Thermal effects inside the vibration elastomeric isolators have usually
been neglected and this aspect can leads to certain differences between
simulations and experiments. Continuous damping during the working
cycle ...
