- Abstract:
- Based on vector tools and modeling software,this paper analyzed and summarized the structure characteristics of cicada’s wings.And then the element Beam189 and element Shell93 were used to construct finite element model which could reflect the main characteristics of cicada’s wings.The mechanical properties of cicada’s wings in gliding state were simulated and analyzed.In that state,the whole structure of cicada’s wings was found warping shape,and the maximum deformation and stress were close to the far nervure.With the change of sectional size of all kinds of nervure in same ratio,comparative calculation was done to obtain the maximum deformation of the corresponding cicada’s wings.The results showed that the increasing of cicada’s wings’ deformation corresponding to three kind nervure were 121.3％ 、34.8％ 、17.4％ respectively,so their contribution to the stiffness decreased.Among them,front nervure provided main stiffness for cicada’s wings.With the change of the quality coefficient of reinforcement nervure,modal analysis was done to analyze the fundamental frequency changes which could prove suppression effect of reinforcement nervure on flutter.When the quality coefficient of reinforcement nervure was 22,the fundamental frequency decreases about 30％.
