Abstract

The viability of the previously presented flexibility-based component mode synthesis (FCMS) of structural dynamical systems1 is reassessed. The present paper offers a historical perspective on the fore method and various CMS methods, and then reexamines the FCMS method against this backdrop. The FCMS method involves two-level model reductions: construction of a reduced order model of each substructure from its individual equations of motion and a reduced order model of the interface degrees freedom via the dynamical residual flexibility equation. The present FCMS method is statically complete just as the Craig-Bampton(CB) method, and naturally amenable for constructing both the individual substructural models and the interface flexibility model to scalable parallelization, which is apparently not easily achievable for the CB method. In addition, the present FCMS method possesses a substructural mode selection criterion that is independent of loading conditions. Numerical examples illustrate the effectiveness of the present FCMS method.
