BULETINUL INSTITUTULUI POLITEHNIC DIN IAŞI Publicat de Universitatea Tehnică „Gheorghe Asachi“ din Iaşi, Tomul LVIII (LXII), Fasc. 4, 2012 Secţia CONSTRUCŢII DE MAŞINI NUMERICAL RESULTS ACHIEVED THROUGH THE DYNAMIC SHAPING OF THE ELBOW JOINT BY PETRONELA PARASCHIV ∗1 and CIPRIAN PARASCHIV 2 1 “Gheorghe Asachi” Technical University of Iaşi, 2 Universitaty of Medicine and Pharmacy “Gr.T. Popa”, Iaşi Received: May 10, 2012 Accepted for publication: June 10,.2012 Abstract. The general analytical shaping of the biomechanical systems can be realized according to the estate of the analyzed system. The stability of the mathematical model of a system, i.e. the determination of the equations that govern its dynamic processes, can be realised from more points of view, out of which at least two are fundamental. It has been noticed that the dynamic analysis can be done, likewise the cinematic analysis, adopting either the structural model with a degree of freedom, or the one with two degrees of freedom, taking into consideration only the flexure-extension move, or for an ampler analysis, two independent moves, flexure –extension and pronation - supination; the dynamic model adopted was the one with a single degree of freedom. Irrespective of the structural model to be adopted, in the case in which the dynamic analysis is supposed to determine the torso of articulation reactions, the vectorial method of bodies separation earlier presented can be applied; in this situation the forces that cannot be analytically or experimentally determined are reduced to a point given by a unique torso (force and moment). Key words: elbow articulation, dynamic analysis. 1. Introduction The analytical shaping of biomechanical systems can be realised according to the analysed system state, therefore: ∗ Corresponding author: e-mail: petrouti @ yahoo. com
