| 摘 要： | 为了考察圆柱型声纳阵拖缆在水下拖曳时,由于尾流中发放旋涡激起的涡激振动情况和有关规律,进行 了试验研究。对不同拖曳速度、拖缆倾角,即拖缆与来流速度之间的夹角和不同直径的拖缆涡激振动进行了测量分析。 结果表明,约化速度、拖缆倾角、拖曳速度等是影响涡激振动的主要因素。试验结果对进一步开展该类课题的研究,对声 纳阵拖缆的设计,提供了技术依据,具有实际价值。 |

| Abstract: | An experimental study on the vortex-induced vibrations of a circular cylinder was conducted to investigate the vibration of the towed-cable when the towed array sonar was dragged underwater. The vortex-vibration was measured when the towed velocity,dip angle between the circular cylider and flow velocity,and diameter were varied. Result shows that the dip angle,the towed velocity and reduced velocity are main influence factors to the vortex-induced vibration of a circular cylinder. The experimental result is valuable to towed-cable design and further study on this subject. |
