摘要
Abstract
The simulation coupling calculation is carried out of solve the problem of inaccurate of fatigue life produced by different loading.Based on a certain thickness of the hollow isosceles trapezoidal,and combined with miner rulers,frequency characteristics and quantitative fatigue life of the wind turbine blades under different loads were analyzed.The results show that the fatigue life caused by the aerodynamic loading is the largest proportion of the cycle fatigue life of the wind turbine blade,and the fatigue life caused by the gravitational loading is the smallest.关键词
