STUDY ON VIBRATION CHARACTERISTICS OF UNCONSTRAINED STAND-OFF LAYER DAMPING STRUCTURE CONSIDERING EFFECT OF ADHESIVE LAYER

Abstract

Abstract: Considering the effect of adhesive layer on the stress and strain in unconstrained stand-off layer damping structure, adhesive layer is equivalent to the isotropic material. The joint simulation method of ANSYS and MATLAB is used to analyze the vibration characteristics of unconstrained stand-off layer damping structure with adhesive layer with adhesive layer parameters. The results obtained by modal strain energy method and control variable method show that the adhesive layer plays a key role in the structural vibration characteristics. Therefore, the choice of adhesive laying unconstrained stand-off layer damping structure should ensure that adhesive layer has good mechanical environment under the premise of choice to meet the best properties of adhesive layer of adhesive products.

Key words: adhesive layer, stand-off layer damping structure, vibration characteristics, modal strain energy method, control variable method
