摘　　要：海上及陆上低风速风电的发展促使风电叶片的长度和根部直径急速增大,随之而来的是超大型叶片根部灌注银纹问题的产生。研究表明叶片根部灌注的银纹问题主要发生在树脂灌注固化过程。本文通过研究调整叶片根部树脂灌注固化产生的内应力,减缓叶片后固化过程的内应力释放,有效地解决了大型风电叶片根部的灌注银纹问题。With the development of offshore and onshore wind power with low wind speed,the length and root diameter of the wind turbine blade increase rapidly,resulting in the problem of large blade root infusion crazing grain.The results show that the problem of blade root infusion crazing mainly occurs in the resin infusion curing process.In this paper,by studying and adjusting the internal stress of resin infusion and curing at the root of blades,the internal stress release during the post-curing process of blades is slowed down,and the problem of blade root crazing is effectively solved.
