摘要

The dynamic response of a basic, generic, multilayered,composite vehicle hull with a large, circular opening for theturret assembly has been compared with that of an equivalentsingle-layer, basic metallic hull with identical geometry to assessthe influence of a multilayered, composite armor panel structureon the modal response. Both models, without the engine block,mountings, transmission, and base support system consisting oftracks, wheels, sprockets, torsion bars, etc., were generated usingPATRAN 3 to facilitate computational modal analysis andcomparative evaluation of the influence of multilayeredconstruction on the free vibrational response.
