Modal Analysis of Folding Wings of Imitating Insect Micro Air Vehicle
In nature,beetles use flapping wings to fly,and they have excellent flight performance.The modal characteristics of the folded wing have an important influence on the aerodynamic characteristics of the aircraft.It analyzes the requirements of flap-ping wing motion for wing modal performance,and establishes a finite element model for the folded wing.The modal analysis of the folding wing is carried out,and the modal characteristics of the folding wing under different parameter conditions are ob-tained.Through orthogonal experimental,the significant influence of each parameter on the modal mode of the folded wing is an-alyzed.The result analysis shows that the elastic modulus and thickness of the folded wing have a significant influence on the nat-ural frequency of the folded wing.The research results of this paper lay the foundation for the design,manufacture and practical application of the beetle-like micro-aircraft.
