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 ...
Dextrous Hand-Grasping Preshaping
(Universitatea "Dunărea de Jos" din Galați, 2007)
The research conducted in human grasping have emphasized three main phases: the
visual location of the target, when the object is analyzed an recognized, the reaching
phase of grasping, when the hand preshapes in order ...
The Energetic Analysis of Hydraulic Actuators Used for Small Mobile Cranes
(Universitatea "Dunărea de Jos" din Galați, 2007)
The paper presents applied usual solutions to the action of light self-propelled
cranes, up to 6 tf. It is accomplished an analysis of usual solutions of action and
more over of comanding the equipment. It is analized ...
A Model of the Mechanical Waves in Curved Bars
(Universitatea "Dunărea de Jos" din Galați, 2007)
The different classical models of the mechanical waves in bars
cover every a single type of the wave, respectively only longitudinal,
transversal, inflexion or torsion wave and only in a rectilinear bar, every
with his ...
Study of Noise Produced by Elevators Inside Buildings
(Universitatea "Dunărea de Jos" din Galați, 2007)
This paper studies the way in which elevators movement produces work
perturbing noises. The studies were made on two types of buildings: a
modern building, with noiseless elevators and another one with old
elevators. ...
Influence of the Road Dislevels Upon the Traction System of the Self-Propelled Machines
(Universitatea "Dunărea de Jos" din Galați, 2007)
The kinematic response is caused by run away about the equipment of the
movement modeled in the mechanic system with degree of freedom. The kinematic
excitation considered produces harmonic formally to the organ axle of ...
The Grinding Charge of Rotary Mills
(Universitatea "dunărea de Jos" din Galați, 2007)
This paper presents the achievemens of grinding charge for the tube mills
with balls.The author shows charactheristic size of grinding media
charge: bulk density, porosity, filling degree. Regarding this last size,the
author ...
All-Purpose Low Frequency Numerical Filter
(Universitatea "Dunărea de Jos" din Galați, 2007)
A real signal is a complex system with mixed components. In
addition to needed components appear unusable components with different
origin, namely noise. The clearance or the reduction of the unwanted
components is ...
3D Modelling a Spur Gearing with Solid Edge
(Universitatea "Dunărea de Jos' din Galați, 2006)
The software Solid Edge software is a useful 3D computer aided design (CAD)
running under Windows. The commands and icons of Solid Edge software offer the
possibility to design various solids. In this paper are presented ...
The Idenfication (In Simulink) of an Elastic
(Universitatea "Dunărea de Jos" din Galați, 2007)
In this paper is realized the identification of an elastic system with one degree of
freedom, for which we experimentally pick up (in SIMULINK) the resonance curve.
The system parameters (m, c, k) are determined using ...
