摘　　要：以中国自行设计的某MW级风机轮毂为研究对象,先对轮毂进行拓扑优化,验证拓扑结构,然后对轮毂进行自由尺寸优化,给出一种新型的轮毂结构,使得轮毂重量减少18.6%。优化后的轮毂不但节省材料的消耗,而且使得轮毂强度增加51.4%,疲劳寿命满足使用要求。By taking a MW hub designed by Chinese expert as the research object, firstly, makes topology optimization to verify the hub topology structure of the hub, and gives the free size optimization of the hub, finally, a new hub structure is given, and the weight of the modified hub decreased 18.6% compared with original hub, the modified hub can not only save material, and the increase in static strength was 51.4% ,and the fatigue life of hub satisfy the use requirement.

关 键 词：有限元法 拓扑优化 自由尺寸优化 轮毂
