Computational Dynamics of the Elastic Antivibrational Systems with Non-Linear Stiffness

Abstract

In this paper the author present a set of mathematical models, usable to simulate and analyse the static and dynamic behaviour aspects, both for the passive antivibrational and anti-seismical systems, and for all the machines and equipments that have movements on the unarranged roads, in the length time of a technological process. For all the considered models the author have write the characteristic system of movement equations and present the numerical simulation results, with taking into account the real equipments input data. The author was maded an analysis about the influences of the non-linear type stiffness on the dynamic behaviour of the antivibrational and antiseismical passive isolation equipments, with the impact on the dynamic performances of these protection systems. Also, it was analyse and evaluate the static and dynamic characteristics of these systems because it is very important to protect both the human resources, and the equipments, against vibratory pollution or seismical waves.
