摘要
用磁流变阻尼器支承磁悬浮轴承,可通过控制磁流变液流变性减小轴承转子系统的振动。由于磁悬浮轴承与磁流变阻尼器均有工作磁场,对两种磁场之间的解耦及对磁流变阻尼器磁路的设计,是支承磁悬浮轴承的磁流变阻尼器设计关键。本文首先对两个磁场进行了解耦,在初步设计磁路时使用解析法对磁路进行了计算,并与有限元法进行比较,肯定了解析法在磁路初步设计中的有效性。
The MR damper could provide additional damping for the magnetic bearing-rotor system and reduced the vibration greatly.There are two kinds of magnetic field when using magneto-rheological damper supporting magnetic bearing.The decoupling between the two types of magnetic field and the magnetic circuit design is the key of designing magneto-rheological damper.In this paper decoupling of the two types of magnetic field was performed first,and the magnetic circuit was calculated using analytical method in the preliminary design.By comparing to the finite element method,this paper confirmed the effectiveness of the analytical method in the magnetic circuit preliminary design.
