... large computation scale. The demands of simulation efficiency improvement created various studies on reduced-order modeling (ROM) of multibody dynamics. The component mode synthesis (CMS) is widely used to reduce the degrees-of-freedom (DOF) in the linear system [ 22 ]. The approaches of CMS are divided...

... and the damping terms in the reduced-order model (ROM). We show the applicability of this model to all planar motions of the airfoil; heaving, pitching, and flapping. With increasing the Strouhal number, the nonlinear damping terms for all types of motion approach similar magnitudes. Another important aspect...
