The Effect of the Costal Vein Configuration of the Wings of a Dragonfly
In generally, it is known that structures of living thing are optimized. The wings of a dragonfly are thin and light. Although it is having the structure of bearing the load produced in the case of an advanced flight such as “Flapping flight”, “Glide”, and “Hovering”. The wings of a dragonfly are made by veins and membranes. In addition, the wings of a dragonfly have some characteristic structures, such as “Nodus”. Thus, the wings of dragonfly have many complicated structures. The configuration of costal vein of the wings is different from them of other insects. So, we paid attention to the configuration of costal vein of the wings. Therefore, in this study, we researched about the effect of costal vein. As a result, it was showed that the configuration of costal vein became bending and torsional deformation small. In addition, it was showed that the configuration of costal vein related to nodus. In this study, several 3-D models of the dragonfly’s wing were made and calculated by the 3-D finite element method.
