Research on 2MW wind turbine in the three conditions of modal analysis based on ANSYS
In order to prevent a phenomenon of the working wind tower turbines dumping and fracturing, We had done the modal analysis for wind power tower in this paper. By introducing FEA ( Finite Element Analysis) methods, the finite element model, simulating actual working conditions on the computer and can rationally solve the phenomenon above. And then, we had made modal research for wind tower turbine on three working conditions(V=10.6m/s,25m/s,75m/s). Empirical results show that wind power tower turbine can run safely on three working conditions and meet the strength and stiffness requirements of design at the same time. Through to do modal analysis for the 2MW 69m wind tower turbine, the modal results show that the lower modes frequency are dominant while the contribution of higher modes frequency of response is very small. In short, the 2MW 69m wind tower turbine met the designing and running requirements in this paper.
