摘要
该文提出一种新型的磁阻式磁力悬浮系统,并分析其结构和悬浮原理。采用有限元方法分析了该系统的磁密分布情况,悬浮体受到的轴向、径向和总体悬浮力大小及其随位移的变化关系,仿真结果表明该系统能够产生足够大的悬浮力,在轴向上是被动悬浮的,不需外部控制。仿真结果验证了该系统的可行性和理论分析的正确性,为该系统的进一步研究及其工业应用提供参考。
A novel detent-force-based magnetic suspension system （DMSS） was presented. The topological structure and operating principle of DMSS were analyzed. Using finite-element analysis method, the magnetic field distribution and the characteristics of the axial, radial and whole levitation force with the displacement were studied respectively. The simulation results show that the DMSS can generate larger levitation force than common levitation system, and its levitation mode is a passive suspension in the axial without external control. The feasibility and theoretical analysis of the DMSS were verified. It is helpful for the further analysis and industrial applications of DMSS.
