| Summary: | 碩士 === 崑山科技大學 === 機械工程研究所 === 92 === People used the Micro Air Vehicles to patrol the military activity or explore the danger region. The important parts of Micro Air Vehicles are the flapping mechanisms those can simulate the wing-motion of flying being. Hence this work is to present a systematic approach for designing new flapping mechanisms with one degree of freedom that can simulate the wing-motion of long ear bats and insects. First, we analyze the topological structure and motion characteristics of existed flapping mechanisms. Then, the design criteria of the topological structure and motion characteristics are described. Based on the design criteria of topology, the Yan’s methodology of mechanism design is applied to synthesize new flapping mechanisms. And, the kinematic equations of those new mechanisms are derived. Furthermore, the minimum error between the wing-displacements of new mechanisms and long ear bats is selected as the objective function for designing the dimensions of those new mechanisms. And, the kinematic analysis of these new mechanisms is done well. Finally, a prototype of a (5,7) flapping mechanism of insects is built and tested. This research of the provide method can obtain 94 new flapping mechanisms and one prototype of a flying insect mechanism.
