摘要 舰船机械设备在运转时会引起船舶结构的强迫振动,造成船舶结构的损坏,降低船载精密设备的工作精度。因此,舰船隔振技术一直是船舶工业的研究热点。舰船浮筏是一种新型的弹性减振器,它利用弹性阻尼元件将船载机械设备与船体分离,使船载设备的振动无法直接传递到船体,并通过控制和吸收振动源的弹性波达到减振的目的。本文系统分析了舰船浮筏减振器的结构与原理,建立了舰船浮筏的有限元模型,对舰船浮筏的减振特性进行基于Ansys软件平台的仿真研究,并进行了舰船浮筏的相关参数优化。 The mechanical equipment of ship will cause the forced vibration of the ship structure,cause the damage of the ship structure and reduce the precision of the ship's precision equipment.Therefore,it is of great significance to study the technology of ship vibration isolation.The floating raft of ship is a new type of elastic shock absorber.It uses elastic damping element to separate the ship's mechanical equipment from the hull,so that the vibration of the ship's equipment can't be directly transmitted to the hull,and the purpose of vibration reduction is achieved by controlling and absorbing the elastic wave of the vibration source.In this paper,the structure and principle of the floating raft shock absorber are systematically analyzed,and the finite element model of the floating raft is established.The damping characteristics of the floating raft of the ship are simulated based on the Ansys software platform,and the relative parameters of the floating raft are optimized.
