| dc.description.abstract | 隨著再生能源科技的發展，傳統能源的日益枯竭，全球替代能源比例已成持續不斷成長的趨勢。風力發電為其一主要產能方式，而在風力潛能豐富的臺灣，此發電方式也在積極開發中。但在夏秋兩季時有颱風侵襲臺灣本島及外海，如何因應此極端且複雜的風力狀況，並盡量避免風力發電機組的損壞，對本國是較特別卻極為重要的課題。本研究預期藉由曾商轉卻因颱風吹拂而損壞之葉片，觀察其破損狀況，同時以逆向工程所得資訊推估其原先完整模型，其後建立於颱風風況下一系列之分析流程。利用可計算空氣動力之工具，取得風在不同入流情形下施加在葉片的壓力，將之匯進有限元素結構分析軟體，最後得到葉片結構之應力分布，進而與實際葉片作比對分析，探討其受損之原因，提出改善建議，以供國內設計風機葉片之參考。 | zh_TW |
| dc.description.abstract | As the technology of renewable energy keeps developing and traditional energy is consumed day by day, the global proportion of renewable energy constantly goes up. Wind energy is one of the main ways of renewable energy. On the beautiful island, Taiwan, there is also an enormous amount of wind energy resource, from which Taiwan government is developing the related technology to gain electricity. But when it’s in summer or autumn, typhoon often comes to strike Taiwan. How to deal with this ultimate as well as complex situation and keep the wind turbines away from damage at the same time is a special but critical subject to Taiwan. This project plans to observe the damage situation of wind turbine blade caused by typhoon at first, and create the original model by reverse engineering. Afterwards, a serious of analysis process in typhoon circumstances could be constructed. The load, which is the pressure caused by the wind, is computed by CFD method and exported to the structural analysis software. From the result of stress distribution we could compare with the real damage situation to deduce the causes of damage and make some suggestions of modification. | en |
