The Dynamic Analysis of the Inrtial Vibrating Screens Modeled as 3DOF Elastic Systems
(Universitatea "Dunărea de Jos" din Galați, 2012)
The paper proposes an approach of a 3DOF (3 Degree Of Freedom)
dynamic model for the vibrating screens, with the purpose of determining
some impartial criteria for the appreciation of dynamic characteristics of
the ...
Bucket Crusher Equipment with Attachable to the Excavator ARM
(Universitatea "Dunărea de Jos" din Galați, 2012)
This paper aims to find a new solution of the jaw-action bucket crusher equipment
attachable to the excavator arm. The technological operation of crushing needs this
type of equipment for enhancing productivity, enlarging ...
Modal Calculus of the Reinforced Concrete Bridges Modeled as a Rigid Solid Beared on Viscous Elastic Neoprene Supports
(Universitatea "Dunărea de Jos" din Galați, 2010)
This paper proposes an approach of a six degree dynamic model of a rigidsolid with some types of symmetries. These symmetries lead to simplified mathematical models, which are more easily to solve. If the rigid-solid is ...
Theoretical and Numerical Considerations on the Composite Neoprene Used at Vibration and Shock Isolation Isolators
(Universitatea "Dunarea de Jos" din Galați, 2010)
Construction of passive insulation elements in neoprene single microstructure mixture has demonstrated that the isolators can have the necessary elastic characteristics but low internal damping. The reduced scale models ...
Calculation Method of Straight Unsupported (Freely Deformable) Bars Subjected to in Plane Bending Stress
(Universitatea "Dunărea de Jos" din Galați, 2010)
This paper describes a method of determining the cross section arrows and rotations of a straight unsupported bar subjected to bending stress. The straight bar is in a state of static balance while subjected to external ...
Instrumental Analysis of the Reinforced Concrete Bridges Subjected to Dynamic Forced from the Traffic
(Universitatea "Dunărea de Jos" din Galați, 2010)
This paper proposes an approach of the experimental study of the dynamics of a reinforced concrete bridge made by a number of twenty U beams and beared by eighty identical neoprene supports (four bearings for each concrete ...
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 ...
The Undissolved Air Influences on Dynamic Behavior of Hydraulic Driving Systems
(Universitatea "Dunărea de Jos" din Galați, 2010)
This paper is a part of a group of papers which deal with the changes due to the oil - air mixture into the hydraulic actuating systems. The undissolved air into the hydraulic agent of technological equipment actuating ...
Considerations on the Non-Linear Modelling of the Dynamics of the Vibration and Shock Isolators Made from Composite Neoprene
(Universitatea "Dunărea de Jos" din Galați, 2010)
This study presents the results of theoretical and experimental researches and numerical modeling for some composite material structures of neoprene used to manufacture the viscous-elastic supports of the technological ...
Some Aspects of the Calculation of Beams Loaded with Mobile Forces with Variable Intensity
(Universitatea "Dunărea de Jos" din Galați, 2010)
In this article is presented the case of the beams which are loaded by mobile forces with variable intensity along the beam. In this context, after calculus assumptions and calculus model are presented, necessary formulas ...
