本文主要針對10kW等級之水平軸式風力葉片,應用有限元素分析軟體LS-DYNA模擬在葉片達額定轉速(Rated Speed)下,其葉片結構之彎曲(bending)與扭轉(torsion)變形對發電效能的影響;並探討葉片蒙皮(skin)疊層角度,使用鏡射式疊層(Mirror Lay-up)與螺旋式疊層(Helical Lay-up)方式,將葉片蒙皮(skin)疊層設計分成五種類別,指定為A、B、C、D、E五組。結果顯示,疊層設計B對發電效能與結構負載具有最佳表現。於葉片監控方面,採用埋入式製程裝設應變規 (strain gauge) 感測器;同時建立一套無線傳輸之葉片監控系統,並透過實驗測試檢驗系統之可靠度。
The purpose of this work is to study the blade performance of the 10kW Horizontal Axial Wind Turbine (HAWT) on rated speed condition using finite element commercial LS-DYNA with implicit solver. The coupled torsion and bending effects were compared to each other for Mirror lay-ups and Helical lay-ups of the blade skin in detail. Subsequently, the group B shows the good results for the power performance at the rated speed is equal to 267.38 rpm. under 12 m/s wind speed. In addition, this work is also to develop and construct the wireless transmission system in order to monitor the signal from the embedded TML QFLA-5-11 strain gage when blade of the wind turbine is operating. Besides, upon examining numerical and experimental results for static bending test, the error deviation is presented within 10 %. The completed numerical results of power performance for the composite blade are reported and discussed.
