摘 要
在自然界中，风是一种可再生、无污染而且储量巨大的能源。随着全球气候变暖和能源危机，各国都在加紧对风力的开发和利用，尽量减少二氧化碳等温室气体的排放，保护我们赖以生存的地球。我国风力资源丰富，可开发利用的风能储量为10亿千瓦。对风能的利用，特别是对我国沿海岛屿，交通不便的边远山区，地广人稀的草原牧场，以及远离电网的农村、边疆，作为解决生产和生活能源的一种可靠途径，具有十分重要的意义。风力发电机是将风能转换为机械功的动力机械，又称风车。为了要确保风力机在其设计寿命内能够正常地运行，首先必须对风力发电机组的关键零部件展开设计研究。
轮毂是风力发电机的重要组成部件之一，外界风力传给叶片，通过传动机构转化成电能输出，而轮毂就是接收外力并进行转化的连接部件。作为连接件，它要承受复杂的外力及各种恶劣环境带来的破坏，因此要有足够的刚度和强度；同时作为生产需要的产品，在结构上还要满足经济利益的需求。因此要对其在极限状态下进行静强度分析和疲劳分析，得出应力分布情况，找出危险部位。目前，国内对轮毂的自主设计尚是一片空白，本文就是在这样的研究背景下，对1MW风力发电机组的轮毂进行分析。
本文基于有限元法的基本理论，对1MW轮毂进行了以下研究：
①应用三维建模软件Pro/e创建轮毂几何模型，并与某企业提供的图纸对比，确保模型正确。
②基于有限元分析理论，运用有网格划分软件HyperMesh对模型进行细致的网格划分。本论文采用六面体网格划分形式，主要考虑到六面体比较容易接近模型的实体结构，使分析结果更具合理性。
③运用有限元分析软件Patran对网格模型进行静强度和疲劳分析，算出最大应力及应变，并将结果与某企业1.5MW的轮毂分析数据进行比较，从而验证了本文分析方法的正确性。
本论文运用了有限元分析的方法，并且使用了工作质量较高的有限元分析软件，通过与某企业对轮毂的分析结果比较，证明了该方法的可靠性。本文的分析结果对生产制造有很高的利用价值，可以降低制造成本，提高生产经济性；提高了我国风力设备技术水平，提高了市场竞争力，促进了国民经济的发展。

In this thesis, the use of finite element analysis methods and the use of a higher quality of the finite element analysis software, ensure the reliability results.It has high utilization value for production, lower manufacturing costs and improve production economy; raise the technological level of China's wind power equipment, improve the market competitiveness, promoting national economic development.
