| Abstract: | The rigid-flexible coupling dynamics of a system consisting of a rotating hub and a flexible cantilever beam attached to the rotating hub is reported. The governing equations with the dynamic stiffening terms for this system are derived from the subsystem method reported in this paper. The subsystem method makes the modeling procedure more efficient and the coupling degrees of dynamic equations lower than that of the traditional method' s. An example is given at the end of the paper to validate the presented method. |
