Component model reduction methodology for articulate multiflexible body structures

A two-stage model reduction methodology, combining the classic component mode synthesis method and the newly developed enhanced projection and assembly method, is proposed. The merit of the present methodology is that system models (at various system configurations) assembled using component models obtained via the component mode synthesis techniques are smaller in size than the full-order system models. Hence, this approach alleviates the need to solve large-order eigenvalue problems repetitively. (AIAA)
