Analysis of the Dynamic Response to Stochastic Actions on the Tilting System of the Loader Bucket with Hydraulic Correlator
(Universitatea "Dunărea de Jos" din Galați, 2004)
The resistance encountered by the active organ – the bucket – of the
loader when digging into the material pile is part of the category of
external influences applied to the equipment. Generally this force is not
constant ...
A Solution to a Deflection Beam Problem
(Universitatea "Dunărea de Jos" din Galați, 2004)
The present paper shows how the minimal total potential energy principle
it is used for elastic systems in the case of the determination of the linearelastic
displacements which determines the beams bending. Qualitative
aspects ...
The Coefficient of Restitution in the Plastic Deformation Process
(Universitatea "Dunărea de Jos" din Galați, 2004)
In the analysis of dynamic processes and plastic deformation which appear on the
forging and die forging equipments dint the shocks (forging hammers and screw
presses), it is use frequently theoretical study of de collision ...
About of the Analytical Exactly Solutions of the Differential Equations of the Non-Linear Oscillators
(Universitatea "Dunărea de Jos" din Galați, 2004)
This work presents the manner of the solving of the non-linear differential
equations from order II with the form &y& + p(t)y = q(t)y1-2a . These
equations can characterize the excited vibrations of the mechanical ...
About Concrete Consolidation and Vibration
(Universitatea "Dunărea de Jos" din Galați, 2004)
Proper vibration of fresh concrete is an important process in order to
ensure optimum strength, durability, and appearance of quality precast
products. Accepted practices in the precast industry are unique in some
respects ...
Research Regarding the Investigation of Steel Hardness
(Universitatea "Dunărea de Jos" din Galați, 2004)
Mobile hardness testing is on the advance: in these times of cost pressures
and higher quality requirements there is a quick and economical
supplement to stationary hardness testing in the modern production
process. The ...
Regarding the Efficiency of the Decelaration Through Impedance Coiling of the Hydraulic Cylinders
(Universitatea "Dunarea de Jos" din Galați, 2004)
The paper present a point of view sustained by calculations about the
efficiency of the deceleration system by impedance coiling of the hydraulic
cylinders. It is shown that the simple presentation of the impedance ...
