    • Considerations Regarding the Stability of High-Speed Shafts 

      Dragomirescu, Cristian; Crăifăleanu, Andrei; Iliescu, Victor (Universitatea "Dunărea de Jos" din Galați, 2011)
      The paper studies the problem of the dynamic stability of a high-speed shaft, subjected to bending vibrations. The case of normal machine tool shafts placed on rigid or flexible bearings is considered for different situations. ...

    • Study on the Relationship Between Stability and Energy Efficiency of Hydraulic Excavators 

      Hauk, Niculai (Universitatea "Dunărea de Jos" din Galați, 2014)
      The cycle of operation of hydraulic excavators has a series of steps in which large masses are accelerated and then braked. The presence of additional masses on the excavators improves stability but reduces energy efficiency. ...
