On the Efficiency of Compacting Equipment
(Universitatea "Dunărea de Jos" din Galați, 2010)
In this paper, the efficiency of vibratory rammer during compaction is examined. A three-degree-of-freedom model has been established for analytical representation of the soil-rammer interaction. In the first approach, it ...
About Dynamic Stability Analysis of the Power Regulators With Exactly Hyperbolic Characteristic
(Universitatea "Dunărea de Jos" din Galați, 2003)
Power regulators are attached devices of hydraulic pumps with variable
capacity. Theses have the means to modify the pump capacity depending of
the pressure from the circuit served by the pump. In this way, it result ...
The Character of the Dynamic Processes in the Proportional Servodriving Systems of the Hydraulic Pumps Capacity
(Universitatea "Dunărea de Jos" din Galați, 2003)
The proportional servodriving systems of hydraulics pump capacity are
used in many more applications in tehnological equipments driving. Thus,
the construction of specialized pumping hydraulics units, like the A10VG
and ...
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. ...
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 ...
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 ...
On the Rheological Behaviour of the soil in the Artificial Compacting Process
(Universitatea "Dunărea de Jos" din Galați, 2008)
The artificial compacting of the soil is made mostly with machines with
dynamical action such as vibrating plate, vibrating beater or vibrating
drum. Their effect on the compacting process of the soil has two origins:
the ...
Comparative Analysis Between Operational Performances of Motor Grader Equipments
(Universitatea "Dunărea de Jos" din Galați, 2012)
This paper generally deals with technological equipments for construction
and agricultural works, and evaluated the operational performances for
motor-grader equipments. Starting from a large review of modern ...
