| 摘 要： | 为了进一步减小磁悬浮飞轮的振动力和力矩,建立并分析了一种特殊结构的磁悬浮飞轮的微振动模型,并利用微振动测量平台、数据采集分析硬件和软件,通过试验测量了磁悬浮飞轮6个自由度的振动力和力矩.分析其时域特性和频域特性,其振动特性图(瀑布图)显示了径向两个平动方向X和Y的振动力主要是同频分量、倍频分量以及模态量,其中同频分量较为明显.利用开闭环自适应陷波,分别对X、Y两个方向的振动力进行主动振动控制,取得了较好的控制效果,使得两个方向的振动力的同频量显著下降. |
| 关 键 词： | 磁悬浮飞轮 微振动 主动振动控制 自适应陷波器 |

| Abstract: | In order to effectively eliminate the vibration of magnetically suspended flywheel（MSFW） , the micro-vibration model of a special structure flywheel is built and analyzed. The vibration forces and torques are tested by using micro-vibration plate and data acquisition analysis hardware and software. By analyzing the characteristics of the forces and torques in time domain and frequency domain, their vibration characteristics diagram, i.e. waterfall diagram, shows that the main components of forces in X and Y radial direction are the same frequency components, multiplier frequency components and modal components. The vibration forces in X and Y radial directions are controlled via the open and closed loop adap- tive notch filters, and the results are preferable. |
| Keywords: | magnetically suspended flywheel magnetic bearing active vibration control adaptive notch filter |
