A Solution to a Deflection Beam Problem
(Universitatea "Dunărea de Jos" din Galați, 2004)
The present paper shows how the minimal total potential energy principle
it is used for elastic systems in the case of the determination of the linearelastic
displacements which determines the beams bending. Qualitative
aspects ...
The Coefficient of Restitution in the Plastic Deformation Process
(Universitatea "Dunărea de Jos" din Galați, 2004)
In the analysis of dynamic processes and plastic deformation which appear on the
forging and die forging equipments dint the shocks (forging hammers and screw
presses), it is use frequently theoretical study of de collision ...
About of the Analytical Exactly Solutions of the Differential Equations of the Non-Linear Oscillators
(Universitatea "Dunărea de Jos" din Galați, 2004)
This work presents the manner of the solving of the non-linear differential
equations from order II with the form &y& + p(t)y = q(t)y1-2a . These
equations can characterize the excited vibrations of the mechanical ...
Dynamic Models for the Traction System of the Self-Propelled Machines
(Universitatea "Dunărea de Jos" din Galați, 2007)
The work presents a classification of traction systems as a function of structure,
the systems being classified into: integrally mechanical-tractional systems–STIM,
mechanical-hydrostatical tractional -STMH and integrally ...
Mathematical Models for the Whole Traction Mechanical System of the Technological Self-Propelled Machines

Geometry Stage 3D Modeling of a Heat Station Pump
(Universitatea "Dunărea de Jos" din Galați, 2007)
The paper presents the stages of the 3D modelling of a circulation pump in a
domestic low-power heat station. The possibilities of modifying the geometry
by changing the numerical size of the geometric parameters are ...
Aspects Regarding the Vibrations of the Contacts of a compressed air Switch
(Universitatea "Dunărea de Jos" din Galați, 2007)
The paper studies the vibrations of the contacts of a compressed air
switch, by considering two models. Time variation of the elongation is
presented, as well as spectral representations determined by means of
Fourier ...
Assisted Research of the Rigidity Amplitude of Worm-Gearing Tooth
(Universitatea "Dunărea de Jos" din Galați, 2007)
By means of own software, which evaluates the rigidity of the worm-gear-tooth
system, the paper presents some aspects regarding the amplitude of rigidity. The
study was made on the elasticity characteristic of worm-gearing ...
The Study of the Influence of Stability for Hydraulic Tracked Excavators Excavators with Bucket Using Assisted
(Universitatea "Dunărea de Jos" din Galați, 2007)
The technological process of digging the natural earth using hydraulic
excavators with bucket has the following steps: dislocation, transporting
and depositing in means of transportation. During this process the
excavator ...
