Abstract:	本研究主要是探討拍翼式微飛行器在拍動過程中，如何準確的得知機構運動相對於氣動力訊號之走向，並探討在八字拍翼的過程中，其拍翅振幅長度長寬比值的增減，對升推力及拍翼頻率的影響。夾治具製作係由放電線切割加工製作，另因考慮翅膀上下起始點位置，而設計計數器電路搭配編碼齒輪達成精確的定位。控制程式使用美商國家儀器公司LabVIEW軟體，搭配資料擷取器，完成開發自動化的實驗設備。加上高速攝影機拍攝流場煙線圖並可與量測訊號同步，紀錄拍翼特定位置所產生的氣流走向。微飛行器實驗經由不同風速及電壓控制，完成機構特定位置對氣動力訊號的標記，自動化流程方面也達到效率的提升，減少因實驗步驟及資料後處理分析的繁雜，可加速實驗的進行。本研究也藉由LabVIEW軟體的影像處理模組，完成對拍翼軌跡的寬高比值，對八字拍翼有初步的推論結果。 This study was to investigate the flapping-MAV that how to accurate that body movement relative to the signals to aerodynamic during flapping. And investigate the effect of the thrust, lift force and the wing beat frequency with the aspect ratio of wing span changing during eight-flight. Jigs and fixtures produced by the production of wire electrical discharge machining. Another starting point for considering the wings up and down position, the counter circuit is designed with a code to reach a precise positioning gear. Control program using National Instruments LabVIEW software, match data acquisition device, complete the development of automated test equipment. MAV experiments by different wind speed and voltage control, to complete a specific location on the aerodynamic body of the signal tag. The study also through LabVIEW software for image processing module, to complete the film''s aspect ratio wing trajectory, preliminary inferences on the results of a eight-flight.
