| 中文摘要: |
| 研究造纸机械振动的最理想目标是能采用有效方法对其进行控制。压榨部作为造纸机关键部件之一，对其减振显得尤为重要。文章针对当前国内外高速纸机普遍仅停留于振动监测、故障诊断及采用预知维修方案阶段的现状，在了解压榨部结构特征的基础上，分析其产生振动的原因，提出了相应的减振方法，如降低激励力力幅、隔振、阻振、调谐等被动减振方法和主动减振方法，并从振动理论的角度加以分析。理论研究表明，被动减振方法简单、易行；主动减振方法具有较好的减振效果，且较被动减振方法具有更强的适用性。 |

| Controlling the vibration with effective methods is the ideal target for studying papermaking machinery vibration. It is very important to reduce the vibration of press section which is one of key components of a paper machine. Currently high speed paper machine operation at home and abroad generally only realize vibration monitoring, fault diagnosis and predict maintenance scheme, based on the knowledge of structure characteristics for press section, and the analysis of the reasons of vibration, some suitable methods of reducing vibration of press section were put forward, such as the methods of passive vibration reduction including reducing the amplitude of forces, isolating vibration, damping vibration, tuning and the methods of active vibration reduction, and they are discussed based on vibration theory. The research results indicated that the methods of passive vibration reduction are easy to implement; the methods of active vibration reduction are more efficient,thus, it is more applicable than the methods of passive vibration reduction. |
