DYNAMIC RESPONSE AND ISOLATION DEGREE OF STATIONARY FORCED VIBRATION IN THE CASE OF VIBRATION SUPPORTS WITH COMPLEX VISCOELASTIC BEHAVIOR

Abstract

Through this paper work it seeks to define the dynamic response and the isolation degree of stationary forced vibrations in the case of vibration isolators supports with the complex viscoelastic behavior. For this purpose, it will analyze the following complex viscoelastic models: the viscoelastic model Voigt-Kelvin, Maxwell viscoelastic model and Hooke -Maxwell viscoelastic model (Zener). It is considered that these systems are excited from the outside with a harmonic force. Following determination of differential equations of motion for each model and identify solutions systems of equations can be defined the dynamic response and the isolation degree of stationary forced vibrations.
