the 8-DOFs wind rotor

To verify the feasibility of proposed simplified model, modal analysis of the wind rotor is computed considered the wind rotors in a stationary condition. the modal frequencies of the simplified wind rotor are compared with the corresponding FAST results.为确保所提简化模型的可行性，对风轮进行模态分析，考虑其在静止状态下的风轮。简化风轮的模态频率与相应的FAST结果进行对比。
