| Abstract: | In the light of the structural features and force characteristics of the wind turbine tower,the calculation models of the variable cross-section tube tower are established.Based on the theory of structural dynamics,the formations of the horizontal displacement at the top of the tower and the formula of basic frequencies are deduced.An analysis of the static and dynamic characteristics of the tower and relevant simulated calculation are made by using the finite element software ANSYS.The results show that the finite element model is feasible in engineering application,and the analysis can provide a theoretical basis for structural design of the wind turbine. |
