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
(Universitatea "Dunărea de Jos" din Galați, 2007)
The paper achieves mathematical models of the integral traction mechanical
system, that is the system achieved only with gearings organized in the transmission
components , gearboxes, card differentials transmissions, ...
The Analysis of the Bending Sprigs' Weight Influence on the Resonance Characteristic of the Elastical Mechanical Systems
(Universitatea "Dunărea de Jos" din Galați, 2007)
The Analysis of the Bending Springs' Weight Influence on the Resonance Characteristic of the Elastical Mechanical Systems
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 ...
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 ...
The Mechanical Low Frequency Signal Reconstruction by it's Spectral Components
(Universitatea "Dunărea de Jos" din Galați, 2007)
This paper is a point of view of a new way of signal reconstruction
through it’s spectral components. Sampling theory is analyzed from
different perspectives, what means if for technical reasons the time can’t be
sampled ...
Development of the Multipuiose Thermal Spraying System
(Universitatea "Dunărea de Jos" din Galați, 2009)
Many components and structures require protection against corrosion, oxidization,
excessive heat and wear. This is achieved by applying various types of coatings on
the component base material, hence providing the necessary ...
