Design Guidelines for Vibration Energy Dissipation in Three-Layer Sandwich Cantilever Beams

Abstract

This paper presents an analytical method and provides design guidelines for reducing vibrations in fully covered constrained three-layer beams. The analysis is based on the previous well-established studies carried out to investigate the passive vibration control of structures using constrained layer damping treatment. The main objective of this paper is to present guidance for accurate and appropriate practice in the design of a damped cantilever beam using constrained viscoelastic layers subjected to a harmonic force at its free end. The analysis provides the frequency-reacceptance responses, modal natural frequencies, and loss factors. The provided results depict this information for the first three resonance conditions for a wide range of geometries and material properties. The accuracy of the computed results is validated by comparing them with other published results.
