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 ...
On the Correction Factor for Calibration of the Flowemeters with Axial Turbine
(Universitatea "Dunărea de Jos" din Galați, 2010)
This paper refers to axial turbine flowmeters used for technical measurements of volumetric flows at hydraulic driving systems. This study demonstrates that volumetric flow through the transducer has proportional value ...
Thermical Phase Shift Determination Around Vertical Bridges
(Universitatea "Dunărea de jos' din Galați, 2011)
The way this concept is defined (in the prescription) is not the most proper
for technical regulations where more clear and precise formulations are
required especially when important concepts are defined.
The estimation ...
On the Influence of the Working Tools Shape in the Mixing Proces
(Universitatea "Dunărea de Jos" din Galați, 2011)
Optimisation of the working tools used in industrial factory becomes a fast and effective method to be implemented easier in the production process.
The article presents more design variants of a concrete mixer tools. The ...
