複雜的三維曲面葉片發展至今,為了便於模擬分析,通常是簡化後平板形狀的葉片;但為了符合空氣動力學效率,實際上大部分葉片都是複雜的三維曲面形狀,因此現有的文獻不足以理解此類型問題。 本研究提出一套逆向工程的方法,運用取樣測試得到葉片上不同區域的材料性質,進一步利用所得到的材料性質建構ANSYS 的分析模型,並將彎曲測試結果互相比對驗證差異性。 模擬葉片分別受到風速8m/s、10m/s、12m/s、25m/s穩定狀態流場下的壓力值,接著轉換加載到ANSYS分析一公尺處的變形量,最後使用彎曲測試在相同的變形量得到所需負荷的力量,將此力與ANSYS分析所設定的力互相比較,產生有10.54%~27.95%的誤差值,因此達到驗證的效果。
In order to facilitate the simulation analysis, generally the blade is simplified in flat plate shape. However, in order to conform aerodynamic efficiency, almost blade is 3D complex curved shape, therefore the existing literature is insufficient understanding of this type problems. The research applies reverse engineering method to sample the blade material in order to get the equivalent material properties of complex composite 3D blade. Analysis the blade of wind speed 8m/s、10m/s、12m/s and 25m/s pressure by the steady field, then the data input to ANSYS analysis of the displacement at one meter, finally bending test the load is requited in the same displacement. The numerical result shows there is 10.54% to 27.95% different between the experiment and FE analysis.
