摘　　要：磁悬浮轴承利用电磁力实现定子与转子间的无接触悬浮,集机械、电子、自动控制和电气于一身,是复杂的机电一体化产品,包括了复杂的机械结构和电气控制系统。在根据磁路解析法对主动磁悬浮轴承进行各部分参数的设计时,其磁饱和、磁滞效应以及漏磁等非线性因素均无法考虑,但在实际工程应用中磁轴承的实际性能与这些非线性因素息息相关。结合有限元方法对已设计的磁轴承结构进行电磁性能的仿真分析,研究主动磁悬浮轴承内部的电磁性能并进行结构上的设计校核,为磁悬浮轴承的正确设计提供了理论基础。Magnetic bearing uses electromagnetic force to realize contact-free suspension between stator and rotor.It integrates mechanical,electronic,automatic control and electrical.It is a complex electromechanical integration product,including complex mechanical structure and electrical control system.When designing the parameters of active magnetic suspension bearings based on the magnetic path analytical method,the magnetic saturation,hysteresis effect and magnetic leakage and other nonlinear factors cannot be considered.However,the actual performance of magnetic bearings in practical engineering applications is closely related to these nonlinear factors.In this paper,the electromagnetic performance of the magnetic bearing structure is simulated and analyzed by finite element method,and the internal electromagnetic performance of the active magnetic bearing is studied and the structural design is checked,which provides a theoretical basis for the correct design of magnetic bearing.
