摘要

为正确评估尾流和偏航作用对机组疲劳特性的影响,提出基于时序载荷计算疲劳损伤的评估方法。以风电机组塔筒螺栓为研究对象,对比等效疲劳载荷和累积损伤的雷达图,通过结果分析,证明提出方法的可行性和合理性。应用提出方法,考察不同偏航角、风速和湍流度对塔筒螺栓累积疲劳损伤的影响,进一步验证提出方法的准确性,并得到相应的变化规律。

Abstract

To correctly assess the influence of wake and yaw effects on the fatigue characteristics of the turbine, a fatigue evaluation approach using the fatigue damage calculated by time series load is proposed. The wind turbine tower bolts are taken as the research object. By comparing the radar diagrams of equivalent fatigue load and accumulated damage, and the feasibility and reasonableness of the proposed methodology are proved by analyzing the results. The proposed method is also applied to investigate the effects of various yaw angles,wind speeds and turbulence on the fatigue cumulative damage of the tower bolts while the corresponding rule of change is obtained.
