Vegetal Oils as Lubricating Materials
(Universitatea ”Dunărea de Jos” din Galați, 2008)The success of vegetal oils is related to their biodegradability and reduced toxicity but a wide use is limited by their insufficient stability in time. Biodegradable oils have ecological advantages, being comparable or ... -
Vibration Diagnosis Systems for a Cold Rolling Mill Machine
(Universitatea "Dunărea de Jos" din Galați, 2007)In this work is shown the importance to use a monitoring by vibration system for a cold rolling mill machine. The using of this monitoring vibration system reduce maintenance costs, minimize the impact on operation because ... -
Vibration Measurement Equipment
(Universitatea "Dunărea de Jos" din Galați, 2006)This paper describes the principles of operation of typical instrumentation used in the measurement of shock and vibration. It deals with the measurement of parameters which characterize the total (broad-band) signal. -
Vibrations and Torque Monitoring Processes for a Cold Rolling Mill
(Universitatea "Dunărea de Jos" din Galaţi, 2012)This paper presents researches made on a system of monitoring and other parallel systems for diagnose used in a cold rolling mill. The first system (with specific measurement sensors) is an online vibration monitoring ... -

Virtual Prototype for Simulation and Analysis of Traction Systems in Interaction with Roads
(Universitatea "Dunărea de Jos" dn Galați, 2008)This study deals with numerical simulation of an equipment with full hydrostatic driving system. Based on the clasical mathematical models - single degree of freedom and two degree of freedom models, it was developed a ... -
Viscosity of Amorphous Molecular Substances
(Universitatea ”Dunărea de Jos” din Galați, 2008)Because the great majority of flow units in a liquid behave instantaneously in a solid-like manner, rheological properties of molecular liquids subjected to high pressures may be measured by using corresponding molecular ... -
Voltage Control Scheme for Three Phase SVM Inverter Fed Induction Motor Drive Systems
("Dunarea de Jos" University of Galati, 2010)This paper presents an efficient implementation scheme for the closed-loop voltage control of an induction motor incorporating ‘Space Vector Pulse Width Modulation (SVPWM)’. Voltage control is required to meet the variation ... -

Wear and Irreversible Entropy Generation in Dry Sliding
(Universitatea "Dunărea de Jos" din Galaţi, 2006)This paper examines the relationship between wear and the generation of entropy within the mechanically affected zone, MAZ, of a sliding material. It is postulated that wear is related to irreversible entropy generation ... -
Wear Behavior of Carburizing on Powder Metallurgy Alloys
(Universitatea "Dunărea de Jos" din Galați, 2014)In this paper is studied the influence of wear behavior of carburizing in fluidized-bed on sintered alloys produced by powder metallurgy route. In powder metallurgy, carburization is a thermochemically treatment that ... -
Wear Behaviour of the AL7175 Alloy under Different Bulk Stress States
(Universitatea ”Dunărea de Jos” din Galați, 2008)In what concerns the stresses involved in the process, most wear tests (namely those in the pin on disc and the pin on plate configurations) are usually solely concerned with the stress state in the contact originated by ...
