Paper Abstract

3D displacement and strain measurement for the fast flapping wings is of crucial importance to micro air vehicle design. This research introduces a high-resolution photomechanics testing method for robotic flapping wings. First, the dynamic 3D shape of a fast flapping flight process is reconstructed by the high-speed structured light technique with defocused binary stripe illumination. Then, the 3D displacement map is extracted through geodesic analysis. Finally, the Green- Lagrange strain tensor is computed by Kirchhoff-Love shell theory. Experiments will demonstrate the success of the method by testing a robotic bird with a wings’ flapping frequency over 20 cycles/second.
