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 ...
Methods for Generating Mesh Surfaces Using CAD Systems
(Universitatea "Dunărea de Jos" din Galați, 2011)
One of the most popular graphic software in CAD systems is AutoCAD that is used
frequently by a very great number of users thanks to its numerous advantages. In this paper we present several methods to create mesh surfaces ...
Optimized Method for Synthesis of a Mechanism for Controlling a Hydraulic Operated Machine
(Universitatea "Dunărea de Jos" din Galați, 2011)
This paper presents how can be design a mechanism capable of self
command. It is intended as a high uniformity of the way of action, so that
external control is as safe and simple. Are taken into account the concrete
conditions ...
A Combined Method for Dimensioning Mechanisms Operated with Hydraulic Cylinders
(Universitatea "Dunărea de Jos" din Galați, 2011)
This paper presents a method of synthesis of a mechanism used in ship
steering systems. The case examines the use of force as elements of
hydraulic differential cylinders articulated at both ends. Sizing the
difficulty ...
The Analysis of the CAM Mechanisms Using Matrix Calculations
(Universitatea "Dunărea de Jos" din Galați, 2011)
The present study presents the kinematic analysis of a mechanical
structure created by cam mechanism RR-CC. It was determined the
position, velocity and angular acceleration of the tapped, as depending on
the position ...
Structural and Kinematic Analysis of Planetary Gearings
(Universitatea "Dunărea de Jos" din Galați, 2011)
By bounding two or more gearings, using a role bear-axle element, we can
obtain simple transmissions with caged wheels. A transmission with gear wheels
generally has, an axle of fixed rotation, called main axle. The gear ...
