The Possibilities of Increasing Efficiency and Confidence of the Calculations for Hydraulic Cylinders Provided with Cushioning System at System at end of Race
(Universitatea "Dunărea de Jos" din Galați, 2012)
Working with specialized software, fluid flow analysis has the disadvantage
of being time-consuming. Also, modern computers are needed. This paper
presents a way of combining simulation with specialized programs of ...
A Method for Determining the Pressure Loss Coefficients
(Universitatea "Dunărea de Jos" din Galați, 2012)
For braking elements of mechanisms operated by hydraulic cylinders is
used hydraulic resistance which controls the working fluid. Determination
of these systems is difficult, especially in the design phase. This ...
On the Influence of temperature the Cushioning Ability of the Hydraulic Cylinders
(Universitatea "Dunărea de Jos" din Galați, 2015)
This paper presents some aspects related to the way the cushioning capacity of hydraulic cylinder is affected by the temperature variations of the hydraulic fluid. We have analysed the case of the hydraulic cylinders with ...
The Influence of the Hydraulic Fluid Compressibility on the Tematics of Mechanisms Actuated with Hydraulic Cylinders
(Universitatea "Dunărea de Jos" din Galați, 2015)
the description of the kinematics of mechanisms driven by hydraulic cylinders, hydraulic agent is usually considered incompressible. This computing hypothesis introduces errors which, in certain situations, can not be ...
A Method to Increase the Accuracy Of the Mathematical Model Used to Hydraulically Actuated Mechanical Systems
(Universitatea "Dunărea de Jos" din Galați, 2013-10-01)
In order to achieve mathematical models describing hydraulically driven
mechanical systems are taken into account both consumer behavior and
characteristics of power sources and hydraulic circuits. The variable
resistance ...
A Statistical Analysis of the Danube Flow Regimes in Brăila Harbour Area
(Universitatea "Dunărea de Jos" din Galați, 2015)
It was in the frame of the „Restoration of the aquatic and terrestrial
ecosystems complex, from Fundu Mare Island, part of the Small Wetland
of Brăila - RAMSAR site 1074” project to look for solutions to improve the
hydro ...
An Exact Method for Analysis of Kinematics for Mechanisms by Using Vectors Which Form Closed Polygons
(Universitatea "Dunărea de Jos" din Galați, 2013-05-01)
Construction machinery equipments are complex, with a high degree of
mobility. Their operation is done with groups of hydraulic cylinders equal
in number with the mobility. This paper presents an exact calculation,
which ...
Influence on Energy Efficiency Oof Mechanisms Operated With Hydraulic Cylinders
(Universitatea "Dunărea de Jos" din Galați, 2013-05-01)
During the operation of mechanisms operated by hydraulic cylinders
significant energy losses occur. They is due to the loss of flow, pressure
and friction losses that occur in the system. This paper highlights the
connection ...
Autolisp & DCL Method for Automatic Technological Design
(Universitatea "Dunărea de Jos" din Galați, 2004)
The work has as purpose to present the general principles of working with
the technological processors in designing the casting technologies and to
put into evidence the advantages of this designing method. As examples,
the ...
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 ...
