  • Starețu, Ionel (Universitatea "Dunărea de Jos" din Galați, 2009)
    In this paper, we first discuss issues regarding the training in mechanical design using CAD software to develop the geometric model of the components, the simulation possibilities of functioning in the case of the model ...
  • Picu, Ana (Universitatea "Dunărea de Jos" din Galați, 2009)
    This paper studies the way humans perceive vibrations induced by a running vehicle, starting from Stevens’ Power Law. The measurable physical magnitude was the acceleration transmitted to the hand-arm system. The ...
  • Naidin, Gigi (Universitatea "Dunărea de Jos" din Galați, 2009)
    In order to systematize the three monomobile coupling kinematic chains was essential to find criteria which eliminate those coupling which are inefficient, from the mobility point of view. It is embraced, as main ...

    Within the kinematic study of a rigid solid, its motion is studied faceto- face by a reference system, fixing positions, speeds and accelerations of a reference system, solidarily connected to the rigid solid.
  • Jiang, Zhao-Hui (Universitatea "Dunărea de Jos" din Galați, 2009)
    This paper addresses issues of dynamic parameter identification of robot manipulators. A new identification approach with neural network based compensation of uncertain dynamics is proposed. The parameter identification process ...
