首先介绍了变体机翼及蒙皮结构的发展研究现状,提出了大变形梯形蒙皮结构的构想。随后,建立了梯形蒙皮结构的力学分析数学模型,与有限元仿真分析结果进行了比较和分析,验证了所建立数学分析模型的正确性,为进一步开展制备和实验研究奠定了理论基础。
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.
