Measuring and Controlling of Noises and Vibrations Generated by Industrial Sources
(Universitatea "Dunărea de Jos" din Galați, 2008)
This paper describes a methodology for measuring and control of noises
and vibrations generated by industrial sources, such as: construction
activities, equipments which use vibrations into working process, etc. ...
A New Calculating Method of the Reaction Support Groups Used in Rotary Kiln
(Universitatea "Dunărea de Jos" din Galați, 2008)
This paper presents a new analytical method for calculating the reaction of support
rotary kiln, regarded as an indeterminate static problem. It is the Y -Method and
equation of three displacements (using Y loading ...
Virtual Prototype for Simulation and Analysis of Traction Systems in Interaction with Roads
(Universitatea "Dunărea de Jos" dn Galați, 2008)
This study deals with numerical simulation of an equipment with full
hydrostatic driving system. Based on the clasical mathematical models -
single degree of freedom and two degree of freedom models, it was
developed a ...
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 ...
Characteristics of the Dissipative Hydraulic Joints
(Universitatea "Dunărea de Jos" din Galați, 2008)
This paper analyses the theoretical and experimental characteristics of the
hydraulic energy dissipaters used as dissipative joints for the mechanical
structures subject to earthquakes, and vibrations. The paper allows ...
About the Free Parameter Vibrations of the Mechanical Systems
(Universitatea "Dunărea de Jos" din Galați, 2008)
The oscillation movement of a mechanical non-linear system is not easy to
solve exactly in an analytical way. The approximate solutions are based on different
methods and give different values with different approximation ...

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 Wear Influence on the Working Condition
(Universitatea "Dunarea de jos' din Galaţi, 2003)
During the operation, any machine, equipment, machine parts, or piece, is
submitted to a wear. The evolution in time of the wear size, or, in other
words, a real form for the characteristic of the wear depends on ...
