船舶机舱管路振动原因及原位抑制策略研究
|
摘要
为了解决船舶机舱管路普遍存在的振动剧烈问题,消除管路振动给机舱其它设备性能发挥及船舶航行安全带来巨大隐患,分析了船舶管路振动产生主要原因及机理,针对管路振动的不同类型研究了隔离周边振源、降低流体脉动及避免共振等管路振动抑制的方法。重点研究了在不影响船舶正常航行或影响较小的情况下对管路振动进行原位抑制方法,结合某混装船主柴油机润滑油管路振动抑制实例,探索了振动监测技术和模态测试技术在管路振动原位抑制中的应用,提炼出管路振动原位抑制的一般原则和基本步骤,为船舶机舱管路振动原位抑制提供指导和借鉴。
Aiming to the subject that excessive vibration of ship's pipeline system can lead to other equipment performance reduction and affect the safety of navigation, at first mechanism of ship's pipeline system vibration is analyzed and a method of vibration control is researched. Based on the site layout of ship's pipeline system, situ control technology of pipeline vibration is studied. Taking combination carrier as an example, the pipeline vibration situ control method using modal analysis and vibration monitoring is explored. It provides the reference for vibration situ control of ship's pipeline system in the future.
