| 摘 要： | 以海漂垃圾收集装置浮式围栏的圆柱浮子为研究对象,基于圆柱浮子的浅浸没特性,改进了Morison方程,并结合物理模型试验,对波浪与浅浸没水平圆柱浮子作用问题进行探讨。结果表明,改进的Morison方程可对水平圆柱浮子的波浪力做精确预测,并揭示了波幅、浸没深度以及周期对圆柱浮子波浪力的影响规律。对于浅浸没的圆柱浮子,所受水平波浪力随波高的增大而增大,随周期的增大而衰减到某一特定值。波浪力的正向大小分布要大于负向,而正负向大小的差异主要受浸没深度的影响。

| Abstract: | Based on the partial immersion characteristics of the cylindrical float, the Morison equation is modified, and the interaction between wave and partially immersed horizontal cylindrical float is discussed in depth based on physical model experiments. The results show that the modified Morison equation can accurately predict the variation of the wave force of the horizontal cylindrical float, and the influence of wave amplitude, immersion depth and period on the wave force of the cylindrical float is also revealed. For a partially immersed cylindrical float, the wave force increases with the wave height and decreases to a certain value with the wave period. The distribution of the value of the positive wave force is larger than the negative one, and the difference between them is mainly affected by the immersion depth. |
