摘　　要：载流管路在舰船上有着广泛的应用,其振动对于船舶设备安全以及船舶噪声大小都有较大影响。本文利用有限元软件Ansys的MFX模块,对流固耦合作用下载流管振动进行了仿真分析,并通过振动测试实验对Ansys仿真计算结果进行了验证,二者的一致性较好。The pipes are widely used on aboard,and their vibrations affect the safety of aboard equipments and the noise of ships.In the paper,fluid and structure coupled vibrations of pipe were analyzed by using FEM software MFX,which is a subroutine of Ansys.And the numerical simulation results were validated by vibration measurement experiment.The measurement proves that the calculations are correct.

关 键 词：载流管道 流固耦合 有限元法
