| 摘 要： | 采用扭摆振动振幅测试法，对轴向最大负荷为10kN的转动惯量测试台磁悬浮系统的电磁阻尼进行了实验研究，结果表明该磁悬浮系统中径向电磁轴承的电磁阻尼起决定性作用，同时还采用有限元法和级数法对电磁推力轴承和径向轴承中的电磁场及电磁阻尼力进行了计算，理论计算的结果与实验测量的结果有很好的一致性，由径向电磁轴承计算得到的对数衰减率仅比实验值小18%，转动惯量的计算值与实测值的误差仅为1.09%。

| Abstract: | Electro magnetic suspend system damping of a test rig,whose maximum axial load is 10 kN,for measuring inertia moment has been measured by using twist vibration method,and the results show that the damping force of radial magnetic bearing is dominant. Meanwhile, the finite element method as well as series method is used to analyse the radial and thrust magnetic bearing damping force caused log eddy, the theoretical results are coincided with measurement results. The theoretical logarithmic attenuance from the radial magnetic bearing calculation is about 18% less than measurement results,and the theoretical inertia moment is only 1.09% larger than test results. |
