[en] Unmanned Aerial Vehicle (UA V) structures are
prone to damage during their service lives, caused by
abominable environment factors. Its structural health monitoring
can be effective in reducing maintenance costs and increasing
service life to ensure safe and reliable operation.
Two different damaged modal parameters based on modal
analysis is discussed in this paper in order to develop an efficient
damage identification technique for the UA V wing structures. Its
structure modal is a natural attribute of structures, and
apparently one of the most important parameters of structure
dynamic characteristics. For a well designed aircraft wings
structures, its modal pattern should be continuous without local
mode. Therefore, based on the modal analysis utilizing numerical
methods for a damaged structure, damages location and its
extent can be revealed and damage level can be evaluated.
All the numerical results illustrated these method are efficient
and feasible for structural damage detection. And its can be
utilized in structure
