基于柱型浮标提出新型穿浪式浮标的设计方案,该浮标采用六根中间浮筒代替单一浮筒,并在尾筒末端安装垂荡板,浮标整体采用超高分子量聚乙烯加工。本文使用频域分析法对穿浪式浮标和柱型浮标垂荡方向的运动响应进行对比分析,研究了不同直径的垂荡板对穿浪式浮标垂荡方向的运动响应和附加质量的影响。结果证明:相比于同尺寸的柱型浮标,穿浪式浮标的质量更小,固有频率更大,垂荡方向的运动响应和稳定性优于钢制浮标;通过在浮标尾筒末端加装垂荡板能够显著增加浮标垂荡方向的附加质量,减小浮标垂荡方向的运动幅值,进一步改善浮标的性能和生存能力。
Based on the cylindrical buoy, a new design of wobble buoy is proposed. The buoy uses six intermediate buoys instead of a single buoy and the heddle plate is installed at the end of the tail buoy. The whole buoy is processed by ultra-high molecular weight polyethylene. In this paper, frequency response analysis is used to analyze the motion response of wave piercing buoy and column buoy in the heave direction, and the effect of heave plates with different diameters on the motion response and additional mass of the wave buoy piercing direction is studied. The results show that compared with the same type of cylindrical buoy, the buoyancy buoy is smaller in quality and larger in natural frequency, and has better motion response and stability in the heave direction than the steel buoy. By installing the buoy at the end of the buoy The heave plate can significantly increase the additional mass in the direction of the buoy sailing and reduce the amplitude of the buoy direction, further improving the buoy performance and survivability.
