abstract

This investigation describes a method for both manufacturing a biomimetic insect-sized wing using the photolithography technique and experimentally analyzing its structural dynamic response. The wing geometry of a crane fly forewing is captured using a micro-computed tomography scanner for its replication. A photomask of the membrane and venation pattern is designed from a computer-aided design model developed from the reconstructed scanned model of the wing. The photolithography process is conducted using the negative photoresist SU-8 and the Kapton film to biomimic the veins and the membrane of the crane fly forewing, respectively. A digital image correlation (DIC) system is used in conjunction to a shaker vibrational setup to determine the natural frequencies of the artificial wing from the fast Fourier transform of the time-varying out-of-plane displacement data. Wind-tunnel experiments are conducted using the DIC system to determine the structural response of the artificial wing under different freestream velocities and angles of attack within the regime of insect flight. The vibration modes are dominated by a bending and torsional deformation response. The deformation along the span of the wing increases nonlinearly from the root to the tip of the wing with Reynolds number.
