摘要: 随着风电叶片的大型化,风电叶片轻量化也备受人们关注。腹板作为风电叶片中承受剪力的主要部件,其重量控制对叶片重量影响很大。针对大型风电叶片剪切腹板重量问题,通过对腹板芯材不同的开槽方式对重量和力学的影响进行研究,深入开展工艺性评估、力学评估、产品重量评估。结果表明,夹芯材料不同开槽打孔的加工方式对风电叶片腹板力学影响较小,对工艺性影响亦较小,但对风电叶片减重具有较大影响,对轻量化风电叶片结构设计具有重要意义。

Abstract: With the increasing scale of wind turbine blades, wind turbine blade lightweight is also concerned. As the main component of wind turbine blades, the weight control of shear web also has a great influence on the weight of blades. Aiming at the weight problem of shear webs of large wind turbine blades, the influence of different ways of grooved webs on weight and mechanics was studied to carry out process evaluation, mechanical evaluation and product weight evaluation in depth. The results show that the machining methods of sandwich materials with different grooves and holes have less influence on the mechanics of wind turbine blade webs and less influence on the process property, but have greater influence on the weight reduction of wind turbine blades, which is of great significance to the structural design of lightweight wind turbine blades.

Key words: wind turbine blades; shear web sandwich; the way of the grooves and holes; mechanical property;weight; composites
