摘　　要：风电已成为我国继煤电、水电之后的第三大电源。随着成本下降和补贴退出的发展趋势,成本控制已然成为当前风电领域所面临的迫切需求。风电机组优异的结构不仅质量更轻,对塔筒负担更小,还能节省大量的制造材料。拓扑优化等系列优化手段已经在我国许多工业装备领域有广泛运用,并取得了良好的减重效果,然而拓扑优化技术在风电整机上依然使用较少。本文采用当前国际主流的拓扑优化方法,对大兆瓦级风力发电机组大型承载部件制订拓扑优化轻量设计流程;针对主机架及后机架结构进行实践应用,取得了显著的减重效果,验证了该轻量化设计流程,并通过极限和疲劳强度计算,证明了此方法的的高效性和精确性。Wind power has become the third largest power source in China after coal and hydropower.With the development trend of cost reduction and subsidy withdrawal,cost control has become an urgent demand in the current wind power field.The excellent structure of wind turbine is not only lighter,less burden on the tower,but also can save a lot of manufacturing materials.Topology optimization and other optimization methods have been widely used in many industrial equipment fields in China,and have achieved good weight reduction effect.However,topology optimization technology is still rarely used in wind turbine.The lightweight design process of topology optimization for large megawatt wind turbine castings is developed by using the current international mainstream topology optimization method.The lightweight design process is verified by practical application of the main framework and the back framework,and the efficiency and accuracy of the method are proved by the calculation of extreme and fatigue strength.
