摘要
通过理论分析与数值计算对主动磁悬浮轴承转子磁环的变形和受力进行了研究 ,求出了非对称磁力产生的应力分布 ,进而给出了磁环的位移分布 .利用迭代方法考虑了磁环位移和磁力的耦合作用 ,所得数值计算结果与实际相符 .
This paper studies the deformation and stress of a magnetic ring of an active magnetic bearing through theoretical analysis and numerical computation. The distributions of the stress caused by non symmetry magnetic force are given. The calculation results, which are obtained by using an iterative method and have taken into consideration the coupling effect of the magnetic ring's displacement and the magnetic force, conform with facts.
