Research on large-deformation trapezoidal skin structure of morphing wings

In this paper,the development of morphing wings and skin structures were introduced first.Trapezoidal skin structures with large deformation used in morphing wing were presented so.Then,mechanics analysis theoretical model of the trapezoidal skin structures were established.Theoretical model results and finite element analysis results were compared to verify the validity of the theoretical model.This research will provide a theoretical foundation for structural design,optimization,fabrication process and related experiment.
