摘要:
利用ANSYS Workbench对六环冗余轴向磁力轴承的温度场进行仿真计算,探讨了导致六环冗余轴向磁力轴承温升的原因,分析了磁路面积、磁环侧壁、转子转速等参数对六环冗余轴向磁力轴承温升的影响,给出了六环冗余轴向磁力轴承的结构设计和温升计算方法.研究表明:六环冗余轴向磁力轴承的结构形式对转子的温升影响较大,磁路设计时应该避免导致转子旋转时的反复磁化;失效重构对六环冗余轴向磁力轴承的温升影响较小,可以忽略其影响;六环冗余轴向磁力轴承较原有的两环冗余轴向磁力轴承具有更高的可靠性、力学特性以及较好的热特性.
Abstract:
In this paper,the temperature field of six-ring redundant axial magnetic bearing is simulated andcalculated by ANSYS Workbench and the reasons that result in the temperature rise of six-ring redundant axialmagnetic bearing are discussed. What ’s more,the influence of some parameters such as the magnetic circuitarea,the side wall of magnetic circular,rotating speed on six-ring redundant axial magnetic bearing are ana-lyzed and the structure design and calculation methods of temperature rise are put forward in this paper. Theresults show that,the structure of six-ring redundant axial magnetic bearing has great influence on the temper-ature rise of rotor. When the magnetic circuit is designed,the magnetization of rotor should be avoided. Thereconstruction of failure has small influence on the temperature rise of rotor,which can be ignored. Comparedwith the two-ring redundant axial magnetic bearing,the six-ring redundant axial magnetic bearing has higherreliability,mechanical property and preferable thermal characteristics.
