【 摘 要 】

Recently, there occurs rise and growth of the research on the flapping wing vehiclesby mimicking the biological motion. Its result is so-called the Flapping Micro AerialVehicle (FWMAV). In this thesis, design requirements for FWMAV were establishedby using an analytical tool and unsteady blade element theory (UBET). Based on thepresent FWMAV design requirements, flapping wing mechanism using a six-barlinkage was devised. Moreover, the present mechanisms were analyzed by using theflexible multi-body dynamic analysis to ensure its structural robustness. Bycompleting such procedure, behavior of the present mechanism was estimated. Then,detail design was conducted. Currently, structural analysis regarding the presentmechanism was conducted under the flapping operation in vacuum. And theresulting von-Misses stresses in the linkage were designed to be smaller than theyield stress of the chosen material. After that, detail design and experiment of thepresent FWMAV were conducted for validating the performance, such asaerodynamic force, flapping frequency and flapping amplitude.
