Resistance Study of the Shell of a Wind Turbine Blade
(Universitatea "Dunărea de Jos" din Galați, 2013-10-01)
The paper aims at presening a resistance study on the shell of a wind turbine blade
and highlights the main forces that act on its surface. Femap program with finite
element analysis was used to simulate a linear static ...
A Method to Increase the Accuracy Of the Mathematical Model Used to Hydraulically Actuated Mechanical Systems
(Universitatea "Dunărea de Jos" din Galați, 2013-10-01)
In order to achieve mathematical models describing hydraulically driven
mechanical systems are taken into account both consumer behavior and
characteristics of power sources and hydraulic circuits. The variable
resistance ...
Considerations on the Simplified Numerical Simulation of the Bus Lateral Rollover
(Universitatea "Dunărea de Jos" din Galați, 2013-10-01)
The numerical simulation using finite element method, of the behavior of
buses in case of lateral rollover, requires significant hardware resources
and can lead to the numerical models whose resolution may take
prohibitively ...
Consideration on 2D Constrains for Drawings Made with Existing Design Software
(Universitatea "Dunărea de Jos" din Galați, 2013-10-01)
This paper aims at present the author's personal reasons on the set of
dimensional constraints existing in each design software, that are designed
to achieve certain parametric sketches. In general, constrained ...
Considerations on Design Controls Intended to Achieve Thin Walled Bodies
(Universitatea "Dunărea de Jos" din Galați, 2013-10-01)
This paper aims at presenting a comparative study of the "Shell" command
/ control which generates bodies with thin walls or some equivalent
commands to be found in the following design software packages:
Mechanical ...

the bucket with an increased degree of freedom The assisted design 3D permitted
the optimization of execution model, checking the assembly ...
Comparative Modal Analysis of a Rigid Structure with Conservative Insulation
(Universitatea "Dunărea de Jos" din Galaţi, 2013-10-01)
This paper deals with dynamics of compact rigid structures with elastic
insulation and subjected to various vibratory, shock or seismic actions. It
was supposed a simple rigid model with six degrees of freedom, affected ...
Dynamic Simulation of the Vibrator Roller - Terrain Interaction Using an Elastoplastic Approach
(Universitatea "Dunărea de Jos" din Galați, 2013-10-01)
This study deals with the problematic of deep interaction between the
terrain and the vibratory drum at the technological process of dynamic
compaction. In this paper is briefly presented a theoretical approach of
this ...
