摘要
近年来,风电机组越来越向大型化方向发展,叶片长度迅速增大,这使得风电叶片的动态响应研究越来越重要。本文利用对某MW级风电叶片进行了全尺寸模态试验的研究。之后针对大型风电叶片的特点,利用有限元方法对叶片的模态进行了数值模拟。通过对计算和试验结果的比较,验证了计算方法的可靠性。
In recent years, wind power generators and the blades of them have become much bigger which makes the research on the dynamic response of blades more important. In this paper, a fullscale modal test of a blade for MW turbines was performed and a FEA numerical simulation of made. The process of the simulation was verified with the comparison between the results of testing and calculation.
