Modeling of Nonstructural Components in the Dynamic Behavior of Aeronautical Structures

Abstract : This paper deals with the modeling of the dynamics of nonstructural components in aeronautical structures. It is shown how the overall response in the low to midfrequency is governed by a transfer of energy between the load-carrying structure and the nonstructural components. The effect of these elements can be reproduced by using averaged point transfer functions. A numerical model defined in the frequency domain, capable of depicting such transmission and compatible with standard industrial finite element model, is presented together with an experimental validation.
