Sandwich biskoelastikoen nukleoaren lodieraren eragina igogailu baten erantzun dinamikoan

Abstract

The use of thin viscoelastic sandwiches in terms of vibration attenuation has been widely validated. Sandwich structures composed of viscoelastic adhesive films and metallic constraining layers result in thin composite structures with improved dynamic capabilities. Due to the viscoelastic core, the damping capacity of the sandwich is considerably increased compared to metallic panels. In this work, a numeric model of a lift using viscoelastic sandwiches is presented, in order to evaluate the influence of the core thickness on the dynamic response of a lift. The results show that the thickness of the viscoelastic film determines the vibrational response of the lift.
