【 摘 要 】

This paper examines the effect of different orientation of composite material on the deformation and stress of dragonfly-like flapping-wing micro aerial vehicles (FWMAVs). After billions of years of evolution, insects employing flapping-wing tend to have excellent flight capabilities. To understand the bionic wings will be helpful to design high performance aircrafts. FEM analysis of flapping wing structure simulating dragonfly wings having three layers Epoxy carbon composite material and resin epoxy is glue for adhesive two layers. In the process, the flapping wing model was created in ANSYS Workbench ACP (pre), ACP (post) and then the loading of the flapping wing in each phase will be calculated. Finally, the graphs showing the changes of the maximum deformation displacement and maximum stress can be worked out. It can be known that for the first principle stress, -35° is the best performance because -35° stresses is lowest stress and +35° is the worst performance because this angle is the highest stress. For the second principle stress the -25° is the best performance because -25° have the lowest stress. For the third principle stress, -45° is the worst performance because -45° is the highest stress, +45° is the best performance because here stress is the lowest and 0° is the worst because here stress is the highest. The findings are helpful in answering why insect wings are so impeccable, thus providing possibility of improving the design of flapping wing aerial vehicles. This paper will found why insect wings are impeccable.
