为研究海流冲击对深海采矿装备液压管道流固耦合振动的影响，利用伯努利—梁模型，对内流作用下的柔性管道进行受力分析，建立管道流体流固耦合振动方程。根据有无外部周期性冲击作用力两种情况对液压系统管道进行了仿真。仿真结果表明：(1)外部周期性冲击力加剧了管道内部的油压波动。(2)外部周期性冲击力增大液压管道振动的最大位移。

The Bernoulli-beam model was employed to study the influence of ocean current impact on fluid-structure coupled vibration of the deep-sea mining equipment hydraulic pipeline. Through the dynamic analysis of the flexible pipe-line under internal fluid flow, the fluid-structure coupled vibration equations were established. The behavior of the hydraulic pipeline with and without external periodic impact was simulated respectively. The simulation results show that the external periodic impact can exacerbate the fluid pressure fluctuation in the pipeline and increase the maximum displacement of the hydraulic pipeline vibration.
