風力發電葉片主梁彎扭耦合設計研究

    同時在葉片整體性能上，也進行了檢驗，如表3所示。表中數據表明，碳纖維替代玻璃纖維，主梁利用彎扭耦合進行設計，在鋪層平均厚度減小11.33%的情況下，葉片在結構性能上仍有全面的提高。

    彎扭耦合運用到葉片設計將是大勢所趨，其技術將會逐漸成熟。本文主要對彎扭耦合設計在葉片主梁上的運用做了初步探討對彎扭耦合控制參數進行了研究，推導出了單向層合板最簡潔的耦合控制參數的表達式，并從理論上對彎扭耦合控制參數的變化范圍進行了計算。計算表明，在一定鋪層角度范圍內，彎扭耦合程度對材料十分敏感。主梁上碳纖維替代玻璃纖維，并引入彎扭耦合設計將會使葉片在整體性能有較大提高。
