The operation supports axial blade geometries, which can include a tip clearance near the hub or shroud that is, a gap between the blade tip and the hub or the shroud.
本人做風電葉片部件測試,在參考文獻Failure analysis at trailing edge of a wind turbine blade through subcomponent test中選用近似結構的模型,在未知加載邊界條件的情況下對端面使用MPC約束,將兩側端面參考點與實際加載點用translator剛性連接,對兩側加載點使用connect displacement進行位移加載。
