管路弹性穿舱件减振机理研究及仿真分析

Research on the vibration reduction mechanism of elastic pipe penetration piece and simulation

为解决穿舱管路结构振动及流体介质的噪声激励向船体传递的问题,提出了一种弹性穿舱件的基本结构原理,对其减振机理进行了分析,并通过仿真进行了验证,提出了减振参数的设计原则,为研制减振性能优良的新型弹性穿舱件奠定了基础。

In order to solve the problem that the machinery and liquid vibration transfer from pipe penetration piece to submarine frame,a kind of basic construction principle of elastic penetration piece was put forward.The mechanism of vibration reduction was studyed and simulated.Then the design principle of vibration reduction parameter was obtained that lays foudations for the design and manufacture of new type elastic penetration piece with good performance.
