摘要

为了实现大容量外转子永磁风力发电机组定子轻量化设计目标,针对定子结构特点和运行过程中的载荷工况,对定子刚度和强度进行了系统分析,得到了定子的应力和变形分布,确定了定子的优化区域。在保证定子刚度和强度满足要求的条件下,运用变密度法对其进行初步拓扑优化设计。在此基础上,通过灵敏度分析确定了对定子质量、刚度和强度影响较大的尺寸参数,进行了响应面尺寸优化。优化后定子的最大应力和最大变形均在许可范围内,质量减少了1 199 kg,减重11.25%,实现了轻量化目标。

Abstract

The stator stiffness and strength are systematically analyzed according to the characteristics of stator structure and load condition in order to achieve the goal of stator lightweight design of large-capacity outer rotor permanent magnet wind turbine generator set. The stress and deformation of the stator are obtained,and the optimal area of the stator are determined. Under the condition of ensuring the stiffness and strength of the stator,the initial topology optimization of stator is designed by variable density method. On this basis,the dimension parameters that have great influence on the stator mass,stiffness and strength are determined by sensitivity analysis and optimized by response surface method. After optimization,the maximum stress and strain of the stator are in the allowable range. The mass of stator is reduced by 1 199 kg,which means that it is 11. 25% lighter than the original stator. Therefore,the optimization method studied in this paper works well for the lightweight target.
