摘　　要：为减少轮毂质量、节省制造成本,本文以1.5MW风力机轮毂为研究对象,通过ANSYS Workbench软件平台,以拓扑优化及尺寸优化两种优化方法对轮毂进行了结构优化,并对优化后的轮毂进行了重新建模及极限强度分析。对比分析结果表明,尺寸优化即整体减小壁厚6mm的方法更优,优化后的轮毂满足强度要求,质量比原轮毂减轻了16.01%,节省了材料,实现了预期目标。In order to reduce the hub weight and the manufacturing costs, taking 1.5MW wind turbine hub as the research object, in ANSYS Workbench platform, the hub structure was optimized by combining two optimization methods of topology optimization and size optimization. The model after optimization was rebuilt and the ultimate strength was analyzed. The comparative analysis results show that the size optimization method about integrally reducing the hub wall thickness 6ram is better, the optimized hub meets the strength requirements, and the reducing amplitude in the weight of hub is 16.01%, this method saves materials and achieves the expected objectives.
