摘要
为方便今后风力机叶片气动弹性稳定性问题的判别,进而得到工程上快速应用的方法,通过推导分析得到水平轴风力机叶片气动弹性稳定判别数Shy。结论表明Shy与材料属性、材料分布和叶片运动状态密切相关。最后将应用气动弹性稳定判别数Shy得到的结论与叶片气动弹性问题数值计算的结果进行比较,验证了Shy的合理性。
In order to discriminate aeroelastic stability problem of wind turbine blade easily and get the rapid application method, discrimination number Shy of aeroelastic stability was derived through the movement analysis of horizontal axis wind turbine blade. The results Show that Shy is closely related to the status of material properties, material distribution and movement of the blade. At last comparing conclusion from aeroelastic stability number Shy with numerical computation results, the rationality of discrimination number Shy was verified.
