Abstract

In order to obtain more accurate dynamics response of folding wing, flexible multi-body system method was employed to build the flex-rigid coupling dynamics analysis model. The Craig-Bampton method was modified to describe the flexible wing. Therefore, the boundary effects could be taken into account easily, and the calculation precision was improved. Also, the time varying stress could be gained by means of the modal stress recovery. A given folding wing was analyzed as an example, and the results demonstrated the validity of this method.

Key words： folding wing; dynamic analysis; flex-rigid coupling; stress recovery; Craig-Bampton method
