Theoretichal Considerations about the Maximum Vibration Limits for Wheel Loader Affected by the Ground Conditions
(Universitatea "Dunarea de Jos" din Galaţi, 2003)
In this paper, the author make a study of vibration (vertical acceleration)
into wheel loader who is affected by the ground conditions. It is known
from many studies and investigations, that the drive vibrations are ...
Experimental Study of the Air-Jet Stem Generator
(Universitatea "Dunărea de Jos" din Galați, 2015)
Applications of sound and ultrasound air-jet stem generators became of great interest in heat and power engineering, in environmental protection, in the production of heat insulating material, extraction of poor uranium ...
Quantification of the Dynamic Response of a Viaduct Loaded by Shocks from Road Traffic
(Universitatea "Dunărea de Jos" din Galați, 2012)
The work in seismic design of bridges needs to develop physical models and
mathematical theory, based on which will be assessed and quantified the dynamic
response of bridge structures subjected to stress arising from ...
The Parametrical Free Vibrations of Elastic Systems, the Analytical Exact Solutions
(Universitatea "Dunărea de Jos" din Galați, 2012)
The movements of many material systems can be described by differential
equations that have coefficients that depend on time. It is difficult to
determine the solutions of these equations. Although many concrete
problems ...
Diagnostic of Structural integrity Using the Non-Linear Vibration
(Universitatea "Dunărea de Jos" din Galați, 2007)
The aim of the work presented here was to investigate the possibility of
using hangs in the non-linear vibration characteristics to detect damage
in mechanical structure. The nonlinearities were detected by examining
the ...
About Concrete Consolidation and Vibration
(Universitatea "Dunărea de Jos" din Galați, 2004)
Proper vibration of fresh concrete is an important process in order to
ensure optimum strength, durability, and appearance of quality precast
products. Accepted practices in the precast industry are unique in some
respects ...
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
