电磁轴承在航空发动机应用中设计问题分析

电磁轴承实现了依靠电磁力使转子非接触地“支承”于轴承体内的目的,并具有运动阻力小、无接触摩擦和磨损、功耗低以及寿命长等优点,是磁悬浮原理在机械领域中的应用实例。航空发动机是电磁轴承的主要应用领域之一。介绍电磁轴承及其系统的特点和电磁轴承的一般设计准则、常用技术指标以及在航空发动机中应用电磁轴承的部分设计问题及解决的方法。

Analysis on Design Problems of AMB Applied in Aircraft Engines

AMB can levitate the rotor contactlessly in bearing house with magnetic force. The special features are low resistance, non contact friction and wear, less power consumption and long service life. It is an example of magnetic levitating to be applied in mechanical field. Aircraft engine is one of main applied fields of AMB. The features are described and design criteria of AMB are introduced in the paper. Some design problems are discussed for the application of AMB in the engine.
