Description

technical field [0001] The invention relates to a finite element modeling method, in particular to an insect wing finite element modeling method with flexible wing vein nodes. Background technique [0002] Insect wings are thin but have excellent structural properties. The traditional modeling method regards the wing as an overall structure through scanning images, lacks detailed settings, such as ignoring the diversity of connection modes between wing veins, and consolidates all of them. This method ignores the fact that the arthropod elastin with high elasticity is distributed at the nodes of the wing veins, and cannot accurately simulate the mechanical properties such as the stiffness of the wing as a whole. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention provides a finite element modeling method for insect wings containing flexible wing vein nodes, which at least includes the following steps: [0004] (1) Basi...
