The Calculus of the Equivalent Rigidity Coefficients for the Shafts of the Elastical Systems
(Universitatea "Dunărea de Jos" din Galați, 2008)
The components of the mechanical systems like machines and/or
technological equipment have a certain elasticity or rigidity. Knowing the
rigidity of each component is very important for the studies whose goal is
to ...
Dynamic Analysis of Mechanical Systems. Calculus of the Equivalent Dynamic Forces and Torques
(Universitatea "Dunărea de Jos" din Galați, 2008)
This article presents the physical and mathematical models of
mechanical systems with elastical and/or rigid elements, subjected to
dynamical loads: forces and torques. The aim of the study is to establish
some formulas ...
Considerations on the Nonlinearity Grade of the Nonlinear Mechanical Elastic Systems
(Universitatea "Dunărea de Jos" din Galați, 2012)
The article is taking into consideration a nonlinear model for the damping,
where the damping coefficient has a polynomial variation function of the
velocity. The differential equation of the movements of the non-linear
1DOF ...
Researches on the Acoustic Treatments with Composite Materials Panels at the Frontal Loader MMT45
(Universitatea "Dunărea de Jos" din Galați, 2012)
The article presents the problem of the testing of some protective systems
made of PU foam based composite materials which can simultaneously
meet the following requirements: noise absorption for middle and high
range ...
The Dynamics Analysis of the Forced Steady-State for the Vertical Towers Chillers with Internal Axial Flow Fan
(Universitatea "dunărea de Jos" din Galați, 2003)
This study presents some of the phases of the physical and mathematical
models' elaboration of the vertical tower chillers with a single axial flow
fan, which are used in social and civil buildings to prepare conditioning
air ...
The Noise at Work and the Professional Diseases
(Universitatea "Dunărea de Jos" din Galați, 2007)
This article describes the effects of workplace noise and outlines the
main steps that should be taken to reduce and control noise at work.
Exposure to noise at work can harm workers’ health. The most wellknown
effect ...
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 ...

(Universitatea "Dunărea de Jos" din Galați, 2007)
The Analysis of the Bending Springs' Weight Influence on the Resonance Characteristic of the Elastical Mechanical Systems
The Behavior of Mechanical Model Wheel' S Loader
(Universitatea "Dunărea de Jos" din Galați, 2002)
In this work is described a dynamical model for the tire-suspension system
of wheel loader. This model is based on the subdivision of the global
dynamical system into its physical components: the tire, the wheel, ...
