Effect of Multimaterial Layering on the Response of a Generic Hull Structure

The dynamic response of a basic, generic, multilayered, composite vehicle hull with a large, circular opening for the turret assembly has been compared with that of an equivalent single-layer, basic metallic hull with identical geometry to assess the influence of a multilayered, composite armor panel structure on the modal response. Both models, without the engine block, mountings, transmission, and base support system consisting of tracks, wheels, sprockets, torsion bars, etc., were generated using PATRAN 3 to facilitate computational modal analysis and comparative evaluation of the influence of multilayered construction on the free vibrational response.
