摘　　要：随着磁悬浮技术在超高速超精密加工等高科技领域的应用,可靠性已成为影响其广泛应用的关键因素。如何进一步提高磁悬浮轴承的可靠性是目前国内外研究的热点,而采用冗余结构是提高磁悬浮系统可靠性最重要的方法之一。文章主要研究在体积一定、电流一定的条件下,同心四环轴向磁悬浮轴承的结构优化设计,并利用ANSYS Workbench对同心四环轴向磁悬浮轴承进行电磁仿真分析。通过研究发现同心四环轴承结构的冗余性高于同心单环轴承结构,但是高可靠性是通过降低工作过程中产生的电磁力为代价换取的。With the wide application of magnetic levitation technology in high-tech fields such as ultra-high speed ultra-precision machining,reliability has become a key factor affecting its wide application.How to further improve the reliability of magnetic bearing is a hot topic at home and abroad,and redundant structure is one of the most important methods to improve the reliability of magnetic bearing system.In this paper,the main research is the structural optimization design of the concentric four-ring axial magnetic bearing under the conditions of a certain volume and a certain current,and the electromagnetic simulation analysis of the concentric four-ring axial magnetic bearing using ANSYS Workbench.By researching,the redundancy of the concentric four-ring bearing structure is higher than that of the concentric single-ring bearing structure,but the high reliability is obtained at the cost of reducing the electromagnetic force generated during the working process.
