| Abstract: | In this Paper, we'll discuss a new idea for dynemic design of the structure of windmill tower by combining the theoretical computation witk the experimental results of reduced scale modeling and especially, discuss the reduced dynamic modeling technic of the windmill tower, the wind load on the tower and the similarity transformation of model parameters. Experiments Proved the feasibility of the optimization design-of the tower vibration. |
