    • An Exact Method for Analysis of Kinematics for Mechanisms by Using Vectors Which Form Closed Polygons 

      Hauk, Niculai (Universitatea "Dunărea de Jos" din Galați, 2013-05-01)
      Construction machinery equipments are complex, with a high degree of mobility. Their operation is done with groups of hydraulic cylinders equal in number with the mobility. This paper presents an exact calculation, which ...

    • Controlul procesului de săpare la excavatoarele cu o cupă 

      Curduman, Laurențiu (Universitatea "Dunărea de Jos" din Galați, 2018)
      Excavatoarele cu o cupă sunt utilaje de construcţii cu care se realizează procesul tehnologic de săpare a pământurilor, funcţie care le conferă aplicabilitate în diverse lucrări pe şantierele de construcţii. Datorită ...

    • Influence on Energy Efficiency Oof Mechanisms Operated With Hydraulic Cylinders 

      Hauk, Niculai (Universitatea "Dunărea de Jos" din Galați, 2013-05-01)
      During the operation of mechanisms operated by hydraulic cylinders significant energy losses occur. They is due to the loss of flow, pressure and friction losses that occur in the system. This paper highlights the connection ...
