Abstract The lift force was reported not to be high enough to support the dragonfly’s
weight during flight in some conventional investigations, and higher lift force is required
for its takeoff. In this study, by employing a thin plate model, impact effect is investigated
for the wing deformation in dragonfly flapping during takeoff. The static displacement is
formulated to compare with the dynamical displacement caused by impact. The governing
equation of motion for the impact dynamics of a dragonfly wing is derived based on
Newton’s second law. Separation of variables technique and assumed modes method are More >
