The application of component mode synthesis for the dynamic analysis of complex structures using ADINA

This paper describes how a complex structure is divided into various kinds of substructures which are calculated independently using the ADINA program and, following this, the dynamic characteristics of the entire structure are recombined by the bi-consistent dynamic substructure method which is a free-interface method improved by the authors. Because both the displacement consistent of substructure interfaces and the interface force equilibrium are satisfied by the present method, all interface degrees of freedom in the synthesis equations can be eliminated. Several examples are presented to illustrate the effectiveness of the proposed method.
