Considerations on the Non-Linear Modelling of the Dynamics of the Vibration and Shock Isolators Made from Composite Neoprene

Abstract

This study presents the results of theoretical and experimental researches and numerical modeling for some composite material structures of neoprene used to manufacture the viscous-elastic supports of the technological equipment with dynamic loads. This kind of equipment, which has a high level of vibration and mechanical shocks, can transmit great dynamic forces and mechanical moments to the environment trough the bearings. The analyzed theoretical models are characterized by the rigidity coefficient and by the dissipation coefficient, making obvious the advantages of some types of composite structures. The article presents the amplitude and the power diagrams function of non-linear damping coefficients for some technological equipments.
