中文摘要：

提出一种磁悬浮轴承刚度阻尼的测量方法。通过对转子施加脉冲激振，计算局部时段的电磁力，识别出磁悬浮轴承的刚度和阻尼。仿真和实验研究表明，此方法可有效测量磁悬浮轴承刚度阻尼。

英文摘要：

A identify measurement of stiffness and damping to active magnetic bearing （AMB） system is introduced. When the static suspension rotor was impacted, the equivalent stiffness and damping can be identified use the electromagnetic force validated before during a short time domain. The simulation and experiment result show that it is efficient for this method to measure the stiffness and damping of AMB.
