摘要

小型飛行器由於獨特的機翼設計與飛行方式使得它能夠在特殊環境從事勘查與聯繫的工作。它的機翼的運動模式可有固定翼、旋轉翼、以及拍撲翼等三大類。本研究目的在於分析拍撲翼機構的運動模式、設計與製作具有翅膀且近似鳥類飛行拍打運動的八桿十一接頭拍撲翼機構。
本研究首先探討拍撲翼機構的拓樸構造特性，根據此特性設計與製作一組八桿十一接頭的拍撲翼飛行機構，接著推導運動方程式，進而設計上拍撲角40°及下拍撲角30°的機構運動尺寸，再設計六組不同翼長尺寸的翼形，進行實驗以分析與探討它於飛行時的升力與推力特性。實驗結果證明本研究所提設計與實驗的可行性。

Based on the unique wing and flight motion design, small aircraft can fly under the special circumstances to perform exploration and communication functions. There are three kinds wing design like as fixed wing, rotation wing, and flapping wing for help the flapping wing mechanism to achieve the functions. The purpose of this study is to analyze the kinematic model of flapping wing animals, design and produce a (8, 11) flapping wing mechanism with approximate flight of birds.
First, we investigate the topological structure characteristic of flapping wing mechanisms. According the characteristic to design and produce a flapping wing mechanism with eight links and eleven joints. Then, derived the motion equations of the mechanism to correspond to up stroke angle 40° and down stroke angle 30°. Finally, we design 6 different wing dimensions for experimental analysis and dynamic characteristic for the function achievement. The design and experimental results show the feasibility of the proposed method.
