Dynamic analisys of the parameters of the mechanical systems with structural damping. Viscoelastic sls model. Part 1: amplitude factor

Abstract

The paper proposes an approach of a 1DOF (1 Degree Of Freedom) dynamic model of an elastic mechanical system with structural damping rheologically modeled as a Zener model. This system is perturbated by a harmonic force F(t) = H sinomegat , the dynamic parameter being the amplitude of the forced steady-state vibration and the transmitted force to the base. The parametric dynamic characteristic that is drawn and analyzed is the amplitude factor A(omega,delta).  This study is useful to validate and/or to assess the viscous materials with Standard Linear Solid (SLS) Model behavior
