| 摘 要： | 为了准确评价磁悬浮旋转机械振动的稳定性，有效控制磁悬浮转子振动、提高系统稳定性，提出应用ISO14839标准对磁悬浮旋转机械的振动稳定性进行评价和分析.对ISO14839标准中的振动位移和稳定裕度内容进行介绍，以一磁悬浮轴承转子实验台为例，应用ISO14839标准评价实验台振动位移和稳定裕度等级，分析系统的振动问题和不稳定因素，提出相应的解决方案.实例结果分析得到，实验台振动位移水平为A等级，稳定裕度水平为B等级，验证了ISO14839标准的合理性.

| Abstract: | A vibration stability evaluation method based on ISO14839 standard was proposed for rotating machinery with active magnetic bearings. The method can be used for vibration control and stability improvement. The vibration displacement and stability margin concept in ISO14839 standard were introduced. Then a magnetic bearing rotor experimental platform was used as an example to evaluate zone of vibration displacement and stability margin respectively. The vibration and unstable factors of system were analyzed, and the corresponding solutions were proposed. The evaluation results show that the vibration displacement level of the experimental platform is A, and the stability margin is B. Then the feasibility of ISO14839 standard was verified. |
