摘　　要：在磁悬挂天平偏航控制中,偏航线圈中的电流变化对模型姿态变化影响十分显著.为了提高天平的偏航控制精度,有必要对天平偏航电磁场进行更为精确的分析.该文采用有限单元法对磁悬挂天平偏航电磁场进行了分析,得到了比传统计算方法更为准确的结果,并在实验中进行了验证,从而为磁悬挂天平的偏航控制提供了参考.In the yawing control of MSBS, the model＇s pose is very sensitive to the change in the current density of the yawing coils. In order to improve the control precision of yawing, it is necessary to analyze the yawing electromagnetic field more precisely. This paper uses finite element analysis （FEA） theory to deal with the 2D MSBS yawing electromagnetic field, and obtains a result more accurate than that with traditional methods. The result is proved in experiments, which shows that the study provides a foundation for improving the control of MSBS yawing.
