    • Mathematical Model for Dynamic Behaviour Analysis of the Passive Isolation Systems 

      Năstac, Silviu (Universitatea "Dunărea de Jos" din Galați, 2004)
      In this paper the authors present a set of mathematical models, usable to simulate and analyse the static and dynamic behaviour aspects, both for the passive anti-vibrational and anti-seismical systems, and for all ...
    • Regarding the Efficiency of the Decelaration Through Impedance Coiling of the Hydraulic Cylinders 

      Hauk, Niculai; Dumitrache, Petru (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 ...
    • Research Regarding the Investigation of Steel Hardness 

      Picu, Mihaela (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 ...
    • A Solution to a Deflection Beam Problem 

      Dumitrache, Petru; Hauk, Niculai; Goanță, Adrian Mihail (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 ...
