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 ... -
Humidity Determination in Concrete by Using the Dielectric Method
(Universitatea "Dunărea de Jos" din Galați, 2011)The presence of humidity in the building envelope elements decays their structural and technological properties, favours heat losses and, in time, also the deterioration and degradation of the building. In order to avoid ... -
Influence of Geometric Parameters on Forces in Single Point Incremental Forming Process for Various Parts
(Universitatea "Dunărea de Jos" din Galați, 2011)The purpose of this study was to investigate the influence of geometrical parameters on the forces in two directions in a single point incremental forming process. For this purpose, the authors have chosen three types ... -
Determination of Optimum Operating regimes of Road Vehicles Based on Minimum Fuel Consumption
(Universitatea "Dunărea de Jos" din Galați, 2011)The paper deals with the mathematical calculation which allows the determination of the optimum conditions in operating the propulsion installations with internal combustion engines applied to road vehicles, in the ... -
On the Stresses and Deflections Calculus in Bending the Cylindrical Naturally Twisted Bars, with Constant
(Universitatea "Dunărea de Jos" din Galați, 2011)The present paper deals with some aspects of the stresses and deflections calculus in case of the cylindrical, naturally twisted bars, with constant pitch, on the basis of assumptions on the linear-elastic behavior of ... -
The Power Balance During Cushioning for Hydraulic Cylinders
(Universitatea "Dunărea de Jos" din Galați, 2011)Cylinder hydraulic brake systems to stop the stroke are built with moving parts to reduce the impact intensity. For correct sizing of hydraulic cylinder cushioning system it is necessary to know how components participate ... -
Transducer with Phase Modulation and Adjustable Sensitivity
(Universitatea "Dunărea de Jos" din Galați, 2011)The work presents an easy converter in order to be used at little displacement. The circuit gives two electrical signals with the same frequency and with different phases, dependent on the displacement.Both signals go ... -
Computer-Aided Graphics in Designing otolaryngology (ENT) Instruments
(Universitatea "Dunărea de Jos" din Galați, 2011)The paper presents some aspects related to the application of assisted graphics in medical engineering, specifically in the design of medical instruments for ENT diseases. The stages of making a three-dimensional part ... -
Aspects on the Use of Version Autodesk Inventator 2012 Within Autodesk Inventator Suite
(Universitatea "Dunărea de Jos" din Galați, 2011)This paper aims to present some new aspects in using Autodesk Inventor software within the Autodesk Suite for Industrial Design. A series of steps in making a vice-type assembly are also briefly presented. -
Some Considerations of using Virtual Reality in the Training Process Specific to Disciplines of Applied Mechanics
(Universitatea "Dunărea de Jos" din Galați, 2009)In this paper, we first discuss issues regarding the training in mechanical design using CAD software to develop the geometric model of the components, the simulation possibilities of functioning in the case of the model ... -
A Study on Stevens' Power Law Applied on the Human Perception of a Running Vehicle Transmitted Vibrations
(Universitatea "Dunărea de Jos" din Galați, 2009)This paper studies the way humans perceive vibrations induced by a running vehicle, starting from Stevens’ Power Law. The measurable physical magnitude was the acceleration transmitted to the hand-arm system. The ... -
The Operational Space's Micro-Geometrical Analysis of the R I R II Kinematics Chain
(Universitatea "Dunărea de Jos" din Galați, 2009)In order to systematize the three monomobile coupling kinematic chains was essential to find criteria which eliminate those coupling which are inefficient, from the mobility point of view. It is embraced, as main ... -
The Utilization of 3X3 Matrixes in Setting Kinematics Chains Analysis for Robots Components
(Universitatea "Dunărea de Jos" din Galați, 2009)Within the kinematic study of a rigid solid, its motion is studied faceto- face by a reference system, fixing positions, speeds and accelerations of a reference system, solidarily connected to the rigid solid. -
Dynamic Parameter Identification of Robots Using a Neural Net
(Universitatea "Dunărea de Jos" din Galați, 2009)This paper addresses issues of dynamic parameter identification of robot manipulators. A new identification approach with neural network based compensation of uncertain dynamics is proposed. The parameter identification process ... -
The Boolean Operations with CAD Systems
(Universitatea "Dunărea de Jos" din Galați, 2009)The AutoCAD software is a power computer-aided design (CAD) system that can offers all users of graphics, 2D and 3D objects representation. In this paper, we present the basic Boolean operations that allow adding, ... -
Creating of the Primitive Shapes Using Autocad
(Universitatea "Dunărea de Jos" din Galați, 2009)AutoCAD is one of the most popular graphics programs that was created for the production of technical drawings in the 2d and 3d with a high precision. In this paper we have presented the basic primitives which can be ... -
Development of the Multipurpose Thermal Spraying System
(Universitatea "Dunărea de Jos" din Galați, 2009)Many components and structures require protection against corrosion, oxidization, excessive heat and wear. This is achieved by applying various types of coatings on the component base material, hence providing the necessary ... -
