ON UNITARY RHEOLOGICAL APPROACH OF VIBRATION ISOLATION PASSIVE DEVICES

摘要

This paper deals with advanced simulation methods of passive devices intended for vibration isolation of different dynamic sensitive technical systems. This study supposes an elastomeric material used for isolator core. Various rheological models are used to simulate the overall behaviour of the vibration isolator under different dynamic loads. A finite element method provide better tool with the main condition that suppose an appropriate constitutive law for base material. The authors propose and underlie a unitary rheological model useful both for lumped, and for continuous mass computational models. The main advantage of this model results from the easiness of simulation of different basic rheological behaviors for a single serviceable implementation. It is provided both individual and comparative survey of various dynamical situations.
