某型船轴系异常振动问题处理及启示

Countermeasure of shaft abnormal vibration and its instruction

轴系的设计是推进系统和舰船设计的最重要部分之一。针对某型船轴系出现的异常振动问题,分析原因、提出了处理方法,并经实船验证得出了调距桨推进轴系设计的指导性意见。

Shaft design is one of the most important parts in the design of propulsion system and ship. Aiming at the abnormal vibration of the shaft,this paper analyzes the reason,proposes the countermeasures which are validated by full ship test, and put forwards guidance for the design of the propulsion shaft of controllable pitch propellers.
