Embodiment 1
[0044] This embodiment takes a large horizontal axis wind turbine in China as an example, such as figure 1 As shown, the specific implementation steps are:
[0045] i) First anchor the three cables directly to the tips of the three blades, such as figure 1 (a) A static stator system without redundant degrees of freedom is formed, and the dynamic characteristic analysis is performed to obtain the fundamental frequency of the wind turbine system;
[0046] j) Establish a finite element model for the system and apply a preset wind pressure, on this basis, analyze the linear elastic buckling eigenvalues based on the theoretical equation, and obtain the calculated buckling coefficient and buckling displacement;
[0047] k) Assuming that the total length of the blade is H, the distance from the hub is H / 2( figure 1 (b)), H / 4 and 3H / 4 are equipped with static stator systems, and the dynamic characteristics and buckling analysis are carried out. Finally, the fundamental frequency, ...
Embodiment 2
[0055] This embodiment takes a large vertical axis wind turbine in China as an example, such as figure 2 As shown, the specific implementation steps are:
[0056] i) First anchor the six cables directly to the tops of the six blades, such as figure 2 (a) A space cable system is formed, and the dynamic characteristic analysis is carried out on this basis to obtain the fundamental frequency of the wind turbine system;
[0057] j) Establish a finite element model for the system and apply a preset wind pressure, on this basis, analyze the linear elastic buckling eigenvalues based on the theoretical equation, and obtain the calculated buckling coefficient and buckling displacement;
[0058] k) Assuming that the total length of the blade is H, it is at H and H / 2 from the top of the blade in turn ( figure 2 (b) and figure 2 (c)) The static stator system is set up, and the dynamic characteristics and buckling analysis are carried out. Finally, the fundamental frequency, buckl...
