摘　　要：船舶设备的振动不仅会产生噪声,降低船舶的隐身性,而且会造成船体结构的疲劳损害,使船体焊缝等应力较集中的位置出现结构破坏。本文的研究方向是利用动力学工程算法对船舶典型设备进行振动特性建模和分析,分别对船体、动力系统减速器和主汽轮机的振动特性进行研究,有助于改善典型设备的抗振动特性。The vibration of marine equipment will not only produce noise,reduce the stealth of the ship,but also cause fatigue damage to the hull structure,and cause structural damage to the hull weld and other stress concentration positions.The research direction of this paper is to use dynamic engineering algorithm to model and analyze the vibration characteristics of typical ship equipment,and study the vibration thermal characteristics of ship hull,power system reducer and main steam turbine,which is helpful to improve the anti vibration characteristics of typical ship equipment.
