摘要: 本文对某兆瓦级叶片进行结构分析,对比了使用E玻纤单向布和高模玻纤单向布对叶片重量、刚度、频率和正应力安全系数的影响。结果表明,在保证叶片刚度基本不变的前提下,使用高模玻纤单向布可以使叶片大梁显著减重,提高安全性。

Abstract: This paper analyzed the structure of a MW-class wind turbine blade. The effects of E glass UD fabric and high modulus glass UD fabric on the blade weight, stiffness, frequency and normal stress safety factor were analyzed. The results showed that using high modulus glass UD fabric could reduce the weight of blade spar caps significantly and increase the safety, while the stiffness is basically retained.

Key words: high modulus glass, wind rotor blade, structural analysis, safety factor
