Piezoelectric Actuators for Insect-Like Flapping-Wing Micro Aerial Vehicle

Abstract

Abstract:

Abstract： Flappingwing micro aerial vehicles demand high force, high displacement and low mass actuators. In this paper, the laminated plate theory, the energy method and experimental method were used to derive the displacement and block force, actuator’s equivalent mass, stiffness and damping coefficient. Then the second order lumped parameter model was obtained. The experimental results show that the actual displacement is larger than the theoretical value. According to the transfer function, the bode diagram was mapped whose resonance frequency is 2.540 kHz. Compared with the theoretical value, the error is 0.5%, which proves that the model is valid.

Key words: flappingwing micro aerial vehicle, piezoelectric actuator, lumped parameter model
