中文摘要：

轴承是高速机电设备的核心部件。高温超导磁浮轴承具有载重大、刚度高、抗干扰能力强、无需主动控制等诸多优点，可以实现重载高速运行，因此在高速机电设备中具有巨大应用潜力。文中针对中小型飞轮储能器、离心机、脉冲电机等设备实际工程需求，设计并优化完成了一款小型高速超导磁浮轴承。通过三维仿真程序，对磁浮轴承中超导块材和永磁阵列的组合方式和电磁力进行了计算，并对不同气隙下的轴承性能进行了对比。相较于传统二维仿真计算，三维仿真结果考虑了超导块材的空间位置分布，更贴近实际应用，可以作为工程设计的直接参考。相关设计表明，通过合理优化，小型超导磁浮轴承具备足够悬浮力和导向力刚度，可以满足相关系统的工程应用需求。

英文摘要：

Bearing is the key component of high - speed rotational electromechanical equipment. The high temperature su- perconductive（HTS） maglev bearing has high loading capacity, high loading stiffness, well antijamming capacity, and without the requirement of active control, which make it very suitable for the application in high - speed electromechanical equipment. This article focused on the design and optimality of HTS bearing for the engineering application in middle/small size electromechanical equipment, such as flywheel, centrifuge and pulse motor. A 3 - D simulation program was applied to calculate the array and e- lectromagnetic force of bulk superconductors and permanent magnets, with different working gap. Because of the consideration of spatial position of bulk superconductors, the result of 3 - D simulation is more realistic than that of 2 - D simulation. The results of this article demonstrate that the HTS bearing can acquire enough maglev force and stiffness by optimal design.
