Abstract

A new method is presented to calculate the forced response of coupled substructures using experimentally based component mode synthesis (CMS). The method uses test-derived CMS matrices and the uncoupled forced response of each substructure to predict the coupled-system forced response. This is achieved by considering tbe internal coupling forces and external applied forces on a substructure independently, and superimposing the responses of each. The advantage of tais approach is that any number of applied forces can be present, and these can occur at unmeasurable locations. Periodic excitations are considered, and tbe analysis is performed in the frequency domain. The method is ideally suited for integrating test-derived models with finite element models for forced response predictions. A test case is conducted for a simple plate-beam system. The method is simulated analytically, then conducted experimentally using actual measured data. Good correlation is achieved for both cases.
