摘要: 以旋转覆冰风力机叶片为研究对象,对叶片覆冰状态进行人工试验,根据试验结果建立风力机叶片有限元模型,并对不同覆冰厚度的叶片进行应力和模态分析。分析结果表明:覆冰的变化量与叶片所受应力大小呈正相关关系;覆冰量的不同会使叶片的固有频率发生显著变化,造成风力机叶片的疲劳损伤与变形,验证了人工试验的结果。

Abstract: Taking rotor blades of rotating ice as the research object, the artificial icing test of blades is carried out. According to the experimental results, a finite element model of wind turbine blades is established, and the stress and modal analysis of blades with different icing thickness are carried out. The analysis results show that the amount of ice change is positively correlated with the stress magnitude of the blades. The different natural frequencies of the blades will be significantly changed by the amount of ice, causing the fatigue damage and deformation of the wind turbine blades, which verifies the results of artificial experiments.

Key words: rotating wind turbine blade, modal analysis, ice cover, ANSYS simulation, natural frequency
