| Abstract: | In this paper,some system dynamics equations of the wind turbine rotating blade structure are created by means of modern flexible multi-body dynamics theory and finite element combining with numerical analysis theory,and the numerical solution for differential equations are studied further.A 1.5 MW wind turbine model is established,and the structure dynamics response of the blades is analyzed finally based on BLADED software,and following results and conclusions are gotten from the model simulation,the natural frequency of the system,the three-blade vibration displacement in wielding and shimmy direction under the normal working conditions,starting and parking conditions,and the stability estimation of wind turbine operation. |
