Abstract
Hawkmoth wings consist of veins and membrane elements that undergo large deformations while moving through the air. The intention of this paper is to create an Euler-Bernoulli beam that can model the complex structure of a hawkmoth forewing. The beam undergoes bending and torsion, and its modal analysis and deformation data are validated against those of the wing structure created based on the finite-element method and a biological wing. A multibody dynamics approach is employed to model the deformation of the beam wing when it oscillates at the frequency of an actual hawkmoth.
