摘要
Abstract
Based on ANSYS Workbench, one way fluid-solid coupling of a small water-pumping windmill is analyzed, and considering the calculated wind load on the blade surface, the finite element analysis of static stress is conducted to the windmill blade. Through analysis and comparison of the wind wheel under different working conditions, the stress and deformation laws are worked out. The results show:at rated wind speed of 8 m/s, the maximum equivalent stress is largely distributed in the blade root;the static stress of the windmill blade increases with the wind speedup, which is lower than the allowable stress, however long-term stress concentration at a certain point of the blade will lead to fatigue failure;the deformation of the windmill is in gra-dient distribution, in which major deformation occurs to the blade tip while little deformation occurs to the joint between the wheel hub and the blade.关键词
