摘要

摘要: 轮毂是风电机组重要的受力和传力部件,其强度严重影响到风力机的使用寿命。依据德国劳埃德(GL)风力发电机组认证规范,运用大型通用有限元分析软件MSC.Marc,对某MW级直驱型风电机组轮毂进行极限强度分析,提出了一种能有效模拟风电机组轮毂真实受力的载荷加载方式,并采用修正的雨流计数法和Palmgren-Miner线性累积损伤理论对轮毂疲劳强度进行分析,结果表面,轮毂的极限强度和疲劳寿命均满足20年的工作要求。本文中探索出了基于GL规范的MW级直驱型风力发电机组关键零部件分析的新方法。

Abstract: Wind turbine Hub is an important stress bearing and load transmission components,whose strength seriously affected the life of wind turbine.A load applying manner was provided for the strength analysis of Direct-drive Wind Turbine Hub in this paper,which can simulate the real stress of wind turbine hub effectively.Then the ultimate strength analysis of large Direct-drive Wind Turbine Hub was performed by using finite element analysis software MSC.Marc and the fatigue analysis was calculated by applying modified rain-flow Counting Method and Palmgren-Miner Linear Cumulative Damage Law,both of which were carried out according to the German Lloyd(GL) wind turbine certification standards.The results suggest that the strength of hub can meet the life requirements of 20 years,and the present study explored a new analysis method of key components of direct-drive wind turbine,which provides some basic ideas for the structure design of hub.
