摘　　要：以NREL 5MW风力机叶片为研究对象,基于瓦楞结构对叶片腹板进行创新结构设计,同时在ANSYS APDL中对风力机叶片进行铺层设计。在不改变叶片自身气动外形的前提下实现叶片重量减少和叶片强度提高的目的。通过使用ANSYS静力学模块对叶片进行模态、静力学、弯扭特性分析。研究结果表明:基于瓦楞结构设计的“T”型梁腹板在满足叶片结构强度的同时减轻了叶片的自重,并有效提高了叶片的抗扭性能。In this paper,the improved design of NREL 5 MW wind turbine’s blade was studied.The innovative structural design of the blade web was carried out based on corrugated structure,and the layup design of the wind turbine blades was carried out in ANSYS APDL to achieve the purpose of blade weight reduction and blade strength improvement without changing the aerodynamic shape of the blades.The modal,statics,bending and torsional characteristics of the blades were analyzed with the ANSYS statics module,and the research results show that the"T"beam web based on the corrugated structure design can meet the structural strength of the blade,reduce the weight of the blade,and effectively improve the torsional performance of the blade.
