摘要
针对机载惯性稳定平台电磁轴承的体积、质量较大,电磁场和温度场同时运算的双向耦合法研究较少的问题,提出一种轻量化、大承载磁悬浮机载惯性稳定平台电磁轴承的总体方案,设计了三点式单导磁环电磁轴承支承方式,采用有限元法完成该系统电磁性能的仿真分析,并对结构强度进行校核,完成电磁场和温度场单向、双向耦合的温度场分析。结果表明,电磁轴承性能满足设计要求,磁热双向耦合分析得到的温度分布更符合实际情况,自然空冷的方式能保证系统安全运行。
Aimed at the problems of large volume and mass of electromagnetic bearings for airborne inertial stabilization platform and few studies on bidirectional coupling method for simultaneous operation of electromagnetic field and temperature field,a general scheme is proposed for electromagnetic bearings used in lightweight and large-load magnetically suspension airborne inertial stabilization platform,and a supporting mode with three-point single-conducting magnetic ring is designed for the bearings.The finite element method is used to complete the simulation analysis of electromagnetic performance of the system,and the structural strength is checked to complete the temperature field analysis of unidirectional and bidirectional coupling of electromagnetic field and temperature field.The results show that the performance of the designed bearings meets the design requirements,the temperature distribution calculated by bidirectional magneto-thermal coupling analysis is more in line with actual situation,and the natural air-cooling method can ensure the safe operation of the system.
