摘要：
The high speed rotating prestress makes wind turbine blades produce the dynamic stiffening effect, which has great influence on the strength of the blade and the resonance frequency. The geometric model of the rotor is established in the 3D drawing software. Based on the finite element software, the meshing, the algorithm selection and material properties are discussed respectively. The modal simulation results of the prestressed condition and no prestress state are compared. The dynamic stiffening effect increases the blade original natural frequency.
