Abstract

The article 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. Zener model, also known as SLS (Standard Linear Solid) model, describes the dynamic behavior of a linear viscoelastic mechanical system under a given set of loading conditions. Rheological model is a complex parallel structure, that means: a Maxell model in parallel with a Hooke model. The system is perturbated by a harmonic force F0sinomegat,  the dynamic parameter being the amplitude of the forced steady-state vibration and the transmitted force to the base. The parametric dynamic characteristics that are drawn and analyzed are the transmissibility ratio T(omega,delta) and the isolation degree I(omega,delta).
