The Analysis of Two Simple Composite Structures Using Mechanical Admittance Methods

Abstract

Mechanical admittance methods are applied to two simple composite structures. The mechanical admittance of the composite structures are predicted using the mechanical admittances measured on their constituent substructures. The effects of the suspension system on the measured admittances are estimated. Attention is devoted to the technique of analytically substructures into a composite structure. Resonant frequencies and mode shapes of the composite structures are estimated from the predicted admittances. The effects of modal participation and damping on the estimated mode shapes and resonant frequencies are discussed.
