| Abstract: | In the paper, the static and dynamic characteristics of the 680 mm blade, 905 mm blade and 851 mm blade are calculated and analyzed by using the complete bending twisting beam finite element model and method. The calculating results are in agreement with experiment. It shows that the proposed model and method have their engineering application value. |
