Rheological SLS Model. Dynamic parameters of the mechanical systems with viscous damping. Part 2: transmissibility factor and isolation degree

Abstract

The paper presents the dynamic model of a 1DOF elastic mechanical system with viscous damping rheologically modeled as SLS (Standard Linear Solid) model. The SLS rheological model is a Maxell model in parallel with a Hooke model. The perturbation force F0sinωt is transmitted to the base through both of the elements (Hooke and Maxwell). The analyzed dynamic characteristics are the transmissibility ratio ()ζΩ,T and the isolation degree ()ζΩ,I, function of the viscous damping ratio ζ and the relative frequency Ω.
