ON NONLINEAR EFFECTS DUE TO THERMO-MECHANICAL BEHAVIOUR IN COMPUTATIONAL DYNAMICS OF ELASTOMERIC ISOLATORS

Abstract

This paper deals with heating regime analysis during ordinary and intensive behaviour for a set of anti-vibratory elements based on composite elastomeric materials. The research started from observations and measurements in practice, and contains simulation scenario for some critical cases. Basic aim of this study frames the necessity of dignify the main parameters and their evolution with strength influences on vibration isolation characteristic. It was used classical rheological models with non-linear influence terms. Computational dynamics has performed using finite element method implementation onto the Matlab© FEA toolbox. The results have shown good performances of numerical models according to the experimental tests.
