✦ Synopsis

A three-dimensional ®nite element (FE) model of a multilayered hull±turret assembly of an armored vehicle was generated from major components such as the armored hull, turret and a 105 mm cannon models which were independently developed in PATRAN3 and assembled using rigid-link elements in the ADINA nonlinear dynamic FE code. Smaller components in the experimental vehicle were included as concentrated masses attached to speci®c sets of nodes in the hull corresponding to the actual locations of these components. Addition of these masses resulted in improved correlation between computational and experimental modal analyses.
