磁悬浮轴承磁路结构分析与数学模型建立方法

摘要

The constitution and working principle of the magnetic bearing system are introduced, the magnetic bearings are compared and analyzed from the nature of the control currents, the number of the controlled degrees of freedom, the produce way of the levitation forces, the force ways and the arrange form of the poles. The establishment method and the steps of the levitation forces mathematical models for the magnetic bearings are studied based on equivalent magnetic circuit method, which provides reference for designing the magnetic circuit structure of magnetic bearings and building the mathematical models.%介绍了磁悬浮轴承系统构成和工作原理,从控制电流的性质、受控自由度数、悬浮力产生方式、作用力方式、磁极布置形式等方面对磁悬浮轴承进行了比较与分析,给出了基于等效磁路法的磁悬浮轴承悬浮力数学模型建立方法和步骤,为该类轴承磁路结构设计和建立数学模型提供了参考.
