Correlative Estimations in Using of Effective Configurations for Vibroinsulation Elastomeric Elements
(Universitatea "Dunărea de Jos" din Galați, 2015)
This paper deals with practical insulation devices, systems to provide the tradeoff between the contact with earth (in order to resist to gravitation) and the separation from earth (in order to withstand the earthquake). ...
Geometrical Assumptions Regarding Viscous Fluid Dampers
(Universitatea "Dunărea de Jos" din Galați, 2015)
The specific innovative device presented in this paperwork is a hydraulic system operating with viscous fluid that provides damping for shocks and vibrations. A basic viscous fluid device is constructed on the principle ...
Aspects Regarding Rolling Pendulum Seismic Isolation Systems
(Universitatea "Dunărea de Jos" din Galați, 2015)
Special systems capable to ensure a proper isolation for building structures against dynamic actions have experienced a continuous development in the recent years. These systems are designed to provide increased safety for ...
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 ...
The Dynamics of the Moving Transmissions
(Universitatea "Dunărea de Jos" din Galați, 2015)
The chargers on tire with direction through side-slip are equipments for used loading different materials, having very good manoeuvrability in narrow places due to the possibility of turning around their centre of weight. ...
Some Physical Changes in Extra Virgin Rapeseed Oil after the Process
(Universitatea "Dunărea de Jos" din Galaţi, 2013-10-01)
The aim of this study is the viscosity’s evolution depending on the temperature and the
shear rate and the analysis at the transmittance spectra of the oxidized rapeseed oil.
Rapeseed oil was oxidized at the temperatures ...
Spectrophotometric and Rheological Studies on Oxidized Soybean Oils
(Universitatea "Dunărea de Jos" din Galaţi, 2013-10-01)
This paper presents a rheological and spectrophotometric study of oxidized and nonoxidized
soybean oils at 100, 110 and 120°C temperatures. The oxidation periods of
time were 5 hours and 10 hours. Changes of the oxidized ...
Study on a Seismic Isolation Method Suitable for an Architectural Monument
(Universitatea "Dunărea de Jos" din Galați, 2012)
The research presented in this scientific paper investigates an adaptive
seismic isolation system meant to protect architectural monuments
structures subjected to a variety of seismic ground motions. This scientific
paper ...
Operation Earning Power Modelling of the Manufacturing Process
(Universitatea "Dunărea de Jos" din Galați, 2012)
In order to better represent the specified goal of the manufacturing process we
propose (as a novelty) as a criterion the Earning Power (EP). It is both synthetic
(because it reflects the essential motivation of the ...
