摘要

通过模型比例尺试验研究了振动实体板和穿孔板的水动力系数（附加质量和阻尼）。采用有规则分布的不同直径的圆孔盘，但采用相同的总射孔比。此外，还检查了包含所有这些直径的孔的分形几何形状。在拖曳槽中进行了升力振荡试验和单自由度机构衰减试验。文中还介绍了用WAMIT进行的势流计算。实验结果与文献中可用的数值数据进行了比较，结果表明分形板导致阻尼略大，这是本研究未观察到的趋势。

A comparative experimental study of the hydrodynamic force on a solid heave plate, and on heave plates with regularly distributed and fractally distributed perforations

The hydrodynamic coefficients (added mass and damping) of oscillating solid and perforated heave plates were investigated using model-scale experiments. Discs with regularly distributed circular holes of various diameters, but with the same overall perforation ratio, were used. Additionally, a fractal geometry incorporating holes of all these diameters was examined. The experiments were conducted in a towing tank using heave force oscillation tests and decay tests using a single degree of freedom mechanism. Potential flow computations performed with WAMIT are also presented. The experimental results are compared to numerical data available in the literature, which suggested that the fractal plate lead to slightly larger damping –a trend not observed in the present study–.
