| Popis: | 92 The flapping-wing mechanisms are main elements of Micro Air Vehicles that can be used to patrol the military activity or explore the danger region. Designing the flapping-wing mechanisms is to simulate the wing-motion of flying being. The purpose of this work is to present a systematic approach for designing new flapping-wing mechanisms that can simulate the wing-motion of long ear bats. First, we analyze the topological structure and motion characteristics of existed flapping-wing 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-wing 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 (6,8) flapping mechanism of long ear bats is built and tested. This research of the provide method can obtain 62 new flapping-wing mechanisms and one prototype of flapping-wing mechanism. |
