CONTRIBUTIONS TO THE DYNAMIC STUDY OF ONE DEGREE OF FREEDOM MECHANICAL SYSTEM, ACTUATED BY A HARMONIC FORCE, WITH DIFFERENT ELASTIC AND VISCOUS ELEMENTS

Nicolae URSU-FISCHER, Ioan RADU, Ioana Alexandra MUSCĂ

Abstract


The one degree of freedom mechanical system with a mass subjected to the harmonic force and elastic and viscous elements other than in Kelvin-Voigt rheological model are studied.
The third order differential equations that model the mass displacements were established and also the general solution expression.
The steady-state regimes were studied and the frequency responses were determined.
Based on the frequency response plots one may find the rheological model that has as result the desired movement amplitude during the steady-state period.
