Abstract

In this paper, dynamics of a flexible hub-beam system is studied using a first-order approximation coupling (FOAC) model and the assumed mode discretization method. Three kinds of damping are considered: structural damping of beam material, air damping caused by large motion of the system, and damping located at hub bearing. Validity of the FOAC model is verified by numerical simulations under two cases: (i) known large motion of system and (ii) unknown large motion of system. Damping may significantly affect system dynamics and should not be neglected for high-speed large motion of system or highly flexible beam. © 2008 Elsevier Ltd. All rights reserved.
