| 摘要: |
| 现今高性能伺服系统对系统带宽提出了越来越高的要求，而传动轴、联轴器、减速器等传动机构均存在一定的弹性，使得系统具有一定频率的谐振点。当系统带宽覆盖该谐振频率时，系统就会发生机械谐振现象。尤其对减速器等必然存在传动间隙的传动装置，间隙的存在极大地降低了传动刚度，并加剧谐振带来的危害。在分析伺服系统机械谐振产生机理的基础上，对目前国内外关于抑制机械谐振的各种方法进行了介绍与分析。针对舵系统应用背景指出了几种具有良好应用前景的抑制方法，并着重进行了分析与研究。 |

| Abstract: |
| Nowadays，the need for even higher bandwidth is arising for high performance servo systems.But the mechanical resonance occurres if the bandwidth of servo system covers the resonance frequency which is existing due to the elasticity of transmission mechanism，such as shaft，coupler and reducer，especially for those with transmission clearance in，like reducer.The existence of transmission clearance can largely reduce the rigidity of transmission and intensifies the effect of resonance.In this paper，the causes of mechanical resonance，the advantages and disadvantages of some suppression methods proposed by researchers are discussed.And the ones that have good applicability in electro mechanical actuation system are analyzed in detail. |
