On Nonlinear Computational Assessments of Passive Elastomeric Elements for Vibration Isolation
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2014, Vol 11, Issue 2
Abstract
The area of this study has framed by the passive isolation of the sensitive embedded systems against shocks and vibration due to various technological equipments. This work deals with computational behavior and nonlinear analysis of passive vibration isolation elements based on neoprene. The author presents a set of results gained by numerical simulation of rheological models behaviour under dynamic loads and the effect of parameters changing against dynamic response. It was used both linear and nonlinear computational models. The base isolation principle has used as main hypothesis in all dynamic simulation cases. The single input single output basic model has used in order to provide a simplest way for estimation of system behaviour correlated with parameters changes. This classical model has also adopted to enable the results deployment for a wide range of vibration isolation applications.
