The generalized frequency domain substructure synthesis technique proposed by Jetmundsen et al has been used to predict the combined response of a bare, edge-stiffened plate and two electronic components. This technique offers a substantial advantage over other coupling techniques because it is uniquely suited to handle data sets of varying origin. Of particular interest is the combination of numerically and experimentally derived frequency response data, which is useful for a structural model comprised of components too complex to model using the finite element method. Limitations of the frequency domain techniques are identified and discussed along with potential methods for avoiding these shortcomings. The synthesis results for the plate and equipment show similar shifts in resonance frequency locations and amplitudes relative to the experimental results for the combined structures.
