Abstract

Using an integrated finite element simulation-optimization tool, the design of a multiple zone composite wing is studied to improve its free vibration behavior. The composite structure zones are composed of multiple layers of woven fabrics with different fiber materials and orientations. Results show that a single critical zone in the structure can be identified and used (1) to significantly improve the natural frequencies of the wing regardless of other zones, (2) to perform a frequency tuning with no significant interactions with other zones, and (3) to optimally control the wing's free vibration behavior.
