Rheological SLS model. Dynamic parameters of the mechanical systems with viscous damping. Part 1: amplitude factor

Résumé

The article presents the dynamic model of a 1DOF elastic system with viscous damping, perturbed by a harmonic force ()tsinHtFω=. The rheological model of the damping is Standard Linear Solid (SLS) model, the analyzed parameter being the amplitude factor/ratio, the transmissibility factor and the isolation degree. This study, which analyzes the amplitude factor ()ζΩ,A function of pulsation/frequency ratio Ω and the viscous damping ratio ζ, is useful to validate and/or to assess the viscous materials with SLS model behavior.
