After a general introduction on dynamic loads, in particular stationary-periodic loads, for the dimensioning of aircraft interior, the basic principles of parameter estimation methods in structural dynamics were explained. Based on the shortly described estimation methods, the main part of the contribution focusses on the system identification for different cabin interior monuments, including detailed analysis of the contribution of the sandwich panel material and some of the attachments used on the structures. The tests and some aspects of the analysis were presented for sandwich panels, a doghouse stowage and a single aisle galley. As a short-term outlook, an approach was presented that will help to speed up dimensioning of different monuments based on a modular product structure using dynamic substructuring methods for coupling the separately generated models for each module. The dynamic behavior of each module can be derived directly from test data (without modal synthesis), detailed finite element-models or modal replacement models from scratch. Either way will resort to the system identification testing performed as described before. Further research will focus on the consistent modeling of combinatorial variant product families to further develop the presented approach. © 2012 AIAA.
