Aspects regarding the study of a vibratory device which acts a medical apparatus

Abstract

The paper studies, from the electromechanical point of view, a medical apparatus designed for spine treatment by vibrations. The differential equations of motion of the system have been obtained by using Lagrange equations of the second species, in the form specific to electromechanical systems with electrical part coupled to the mechanical one. The obtained nonlinear differential system has been integrated numerically, considering the cases of undamped and damped free vibrations, respectively.
