Abstract

The aim of this study was to study an improved dynamic modeling method of a whole structure with joints by the Boundary Element Method (BEM). The dynamic model was composed of the elements such as the beam element, plate element, joint element, lumped mass and spring element by the BEM, joints characteristics were introduced to boundary dynamic equations by flexible constraint conditions on boundary. Finally, an improved dynamic model of a whole structure with joints was established based on plate-beam element system mainly. As a result, the dynamic characteristics of a whole structure with joints were analyzed and the comparison of computational and experimental results showed the modeling method was effective. The analyses indicate that the introduced method inaugurates a good way for analyzing dynamic characteristics of a whole structure with joints efficiently.
