  • Dynamic model elaboration for the planetary-precessional gear reducer against vibration 
    DULGHERU, Valeriu; MALCOCI, Iulian (EDP Sciences, 2018)
    The purpose of modern-day machines in general and gear-box in particular is to carry out needs-based on maintenance, good working conditions and to minimize the repair and other servicing downtimes and disfunctionalities. ...
  • Precessional gear-box research regarding vibration activity behaviour 
    MALCOCI, Iulian; TRIFAN, Nicolae; CIOBANU, Radu (Institute of Physics Publishing, 2019)
    An ideal dynamic system in general and precessional transmissions in particular should not generate any vibration, because vibration is equal with loss of energy and bigger sound level emission. In our previously research ...
  • Sound Reasearch in Precessional Transmission 
    MALCOCI, Iulian (Trans Tech Publications Ltd, 2014)
    Sound may be defined as any pressure variation (in air, water or other medium) that the human ear can detect. Just like dominoes, a wave motion is set off when an element sets the nearest particle of air into motion. This ...
  • Vibroacoustical Diagnosis of Planetary Precessional Kinematical Transmission (Part 1) 
    MALCOCI, Iulian; BODNARIUC, Ion (Trans Tech Publications Ltd, 2015)
    An ideal dynamical system should not generate any vibrations, because vibrations mean a loss of energy. Vibration in planetary precessional gear box occurs at bearings, gear wheels, misaligned shafts, imbalance rotating ...
