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 ... -
Analysis of the Anti-Seismic Passive Isolation System Based on the Virtual Prototyping
(Universitatea "Dunărea de Jos" din Galați, 2004)This work propose a new onset for dynamic behaviour analysis of the passive anti-seismic and/or anti-vibrational elastic elements and systems. The basics of this new approach are constituted by the virtual prototyping ... -
Characterization of Bearings Nonlinearities Influences on Viaducts Dynamic Responses
(Universitatea "Dunărea de Jos" din Galați, 2012)In view of viaducts designing and safety exploitation it is necessary to evaluate both theoretically, and instrumentally the dynamic behaviour for impulsive external actions. In this study the dynamic response for a ... -
Comparative Analysis Between Operational Performances of Motor Grader Equipments

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). ... -
Damage Detection at Vibration Passive Isolation Devices
(Universitatea "Dunărea de Jos" din Galați, 2011)This paper deals with some theoretical aspects combined with experimental tests regarding early damage identification in vibroisolation devices. This study was a natural fall-back of an analysis regarding the behaviour ... -
Dynamic Analysis of Electro-Hydrodynamic Vibratory Equipment Using Virtual Prototyping Technique
(Universitatea "dunărea de Jos" din Galați, 2004)In this paper the authors analyse the functional behaviour of an electrohydrodynamic vibratory equipment, that could be used to vibro-driving the piles into the powerless soils, to drive a demolition hammer, a.s.o. ... -
Dynamical Response Analysis of a System with one Degree of Freedom Stresses by the Different Pulse Excitation Functions
(Univeritatea "Dunărea de Jos" din Galați, 2010)Viscoelastic systems embedded in structures such as bridges are subject to various dynamic loading from traffic. A dynamic study of these structures requires more accurate definition of disturbance function parameters: ... -
Influence of the Behavior of Nonlinear viscoelastic Systems Bearing on the Dynamic of Bridge Structures
(Unioversitatea "Dunărea de Jos' dibn Galati, 2011)Modern structures of bridges and viaducts require dynamic isolation systems, designed to eliminate or mitigate the destructive effects of intense traffic and seismic activity on these constructions. This paper studies ... -
Mathematical Model for Dynamic Behaviour Analysis of the Passive Isolation Systems
(Universitatea "Dunărea de Jos" din Galați, 2004)In this paper the authors present a set of mathematical models, usable to simulate and analyse the static and dynamic behaviour aspects, both for the passive anti-vibrational and anti-seismical systems, and for all ... -
Mathematical Model for Frequency-Dependent soil Propagation Analysis
(Universitatea "Dunărea de Jos" din Galați, 2002)Vibration analyses of advanced technology facilities typically must consider frequency as well as amplitude of vibration. A soil propagation model is proposed which will allow the use of site-specific, measurable, frequency ... -
Nonlinear Approaches Regarding Mechanical and Thermal Behaviour of Visco-Elastic Vibration on Isolators
(Un, 2013-10-01)Thermal effects inside the vibration elastomeric isolators have usually been neglected and this aspect can leads to certain differences between simulations and experiments. Continuous damping during the working cycle ... -
Phisycal and Mathematical Model Forvibratory Driving Process Analysis
(Universitatea "Dunărea de jos" din Galați, 2002)Vibratory driving of pile is one of the technologies used for powerless basement soil deep consolidation. This process consist by favouring the pile penetration in soil, whereupon when vibrations using. Experimentally, was ... -
