水下双斜板结构辐射问题的水动力系数研究

Hydrodynamic coefficients of the radiation problem of double submerged inclined plates

本文对一种水下双斜板结构的附加质量和阻尼系数进行了研究。研究中采用的边界元方法可以灵活应用于任意厚度,任意倾角的水下双斜板结构。研究发现:横荡方向附加质量和阻尼系数最大,垂荡方向对倾角变化最为敏感,横荡和横摇方向附加质量和阻尼系数最大值所对应的波浪频率相同。

In this paper, the added mass and damping coefficients of a submerged structure that consists of two in-clined rigid thick plates were studied. The adopted boundary element method in the research can be flexibly applied to submerged double inclined plates with any thickness and any inclined angle. Results indicate that the added mass and damping of sway are the largest,heave is the most sensitive to the change of inclined angle,and the wave fre-quencies of the maximal value of added mass and damping for sway and roll are the same.
