| 摘 要： | 在实际海洋环境中,海底悬空管道的振动受到海洋流体及内部输送流体的作用而具有新的特点。文章建立了受内部流体影响的管道自振特性分析的有限元模型,研究了内流影响管道自振特性的机理,给出了受内流影响的管道固有频率的数值解和避免共振的临界内流速度,为海底管道的使用和维护提供参考。

| Abstract: | At the real ocean circumstance,the vibration of submarine suspended pipeline trends a new characteristic because of the function of ocean current and interior liquid transported.FLM model is set up in the text to investigate the self-vibration characteristic affected by interior liquid.The mechanism of interior liquid affecting the self-vibration characteristic is studied.Numerical solution of the intrinsic frequency and the critical flow velocity to avoid resonance are given.The result can provide certain reference to the application and conservation of submarine pipeline. |

| Keywords: | 3D suspended pipeline self-vibration frequency resonance critical flow-rate |
