【摘要】：离心式冷压机是大型低温超流氦制冷系统的核心部件,其低温、负压环境以及高速条件使得轴承工作寿命受到挑战。高温超导磁悬浮轴承具有载重大、抗干扰性强、无需主动控制等优点,因此应用潜力巨大。针对磁悬浮力与转子动力学性能的综合考虑,提出了一种优化设计方法和悬浮载重比优化指标,基于ANSYS磁场有限元软件,设计并优化完成一款小型高速超导磁悬浮轴承,悬浮刚度达到5.21×10~5N/m。相关结果表明,通过合理优化,超导磁悬浮轴承具备足够的悬浮刚度,可以满足相关应用需求。
[Abstract]:Centrifugal cold press is the core component of large-scale cryogenic superfluid helium refrigeration system. Its low temperature, negative pressure and high-speed conditions challenge the bearing's working life. High temperature superconducting magnetic levitation bearing has many advantages, such as heavy load, strong anti-interference and no need of active control, so it has great potential in application. In view of the comprehensive consideration of magnetic levitation force and rotor dynamic performance, an optimization design method and optimization index of suspended load ratio are presented. Based on the finite element software of ANSYS magnetic field, a small high speed superconducting magnetic bearing is designed and optimized. The suspension stiffness is 5.21 脳 10 脳 10 ~ 5 N 路m ~ (- 1). The results show that the superconducting maglev bearing has enough suspension stiffness and can meet the needs of relevant applications through reasonable optimization.
