本研究係有關於太陽能追日系統之研發,本設計最大的特色在於斜張式結構與十字軸機構之應用,透過斜張式設計可使結構達到輕量與穩固之訴求,而十字軸設計則是掌握了系統的重心,以降低致動器的驅動力及系統的成本。依據創新機構設計流程,首先針對各種追日系統的機構進行廣泛之專利公報與文獻蒐集,並將所收集之內容依機構類型加以分類及分析,其分析結果可作為本研究之參考方向,也可藉此定義出主要之功能需求,並依照功能需求構思出一款新型追日系統之設計,此外透過立體電腦輔助設計軟體來建立追日系統之電腦立體模型,以確認其零件間無干涉之情況,並透過電腦輔助分析軟體來進行結構應力分析,以瞭解在三種不同環境分析條件下的應力分布情況,並於最後進行原型機之製作與測試。
This study is about the research and development of a solar tracking system. The major properties of this design are the applications of the oblique-stretch structure and the cross-axle mechanism. The oblique-stretch design satisfies the requests of lightweight and stability, while the cross-axle design captures system’s gravity center to lower the driving force and the cost. According to the creative mechanism design procedures, patents and literatures about all solar tracking system were collected, classified, and analyzed. The summarized results provided the reference direction of this study and the definitions of major functional requirements. A new solar tracking system was designed according to the functional requirements. CAD software was used to construct the 3D model and to ensure interference-free condition. CAE software was used to perform structural stress analysis to understand the stress distributions under three different working conditions. Finally, a prototype was built and tested.
