Abstract

Floating bodies are widely used in the field of offshore engineering. Existing studies show that the motion responses of a floating body in waves will change with the internal water in the cabins, and it is essential to analyze its hydrodynamic performance under various potential operating conditions. However, most of the research only considers the interaction between the floating body and the internal water in the upright position, and there has been little research on the inclined floating body caused by water partially filled in the broadside. In this study, a floating body with a plurality of longitudinal and transverse cabins was designed. The regular wave model test was carried out in a wave basin, and the numerical results were compared with the experimental results, which verified the accuracy of the model. The effects of wave direction, wave frequency, water filling depth and cabin division on the motion responses of the floating body are analyzed. The results show that the water inside the cabins has a significant impact on the roll motion. With the increase of the water filling depth, the natural frequency of the roll motion decreases. Special attention should be paid to the impact on the wave direction and cabin division on the partially water-filled inclined floating body.

部分充水倾斜浮体的数值与实验分析

浮体在海洋工程领域有着广泛的应用。现有研究表明，浮体在波浪中的运动响应会随着舱室内水的变化而变化，分析其在各种潜在运行条件下的水动力性能至关重要。然而，大多数研究只考虑了浮体与直立位置内水之间的相互作用，而对舷侧部分充水引起的倾斜浮体的研究很少。在本研究中，设计了一个具有多个纵向和横向舱室的浮体。在波浪池中进行了规则波模型试验，并将数值结果与实验结果进行了比较，验证了模型的准确性。分析了波浪方向、波浪频率、充水深度和舱室划分对浮体运动响应的影响。结果表明，舱室内部的水对滚转运动有显著影响。随着充水深度的增加，侧倾运动的固有频率减小。应特别注意部分充水倾斜浮体对波浪方向和舱室划分的影响。

期刊介绍： The Journal of Offshore Mechanics and Arctic Engineering is an international resource for original peer-reviewed research that advances the state of knowledge on all aspects of analysis, design, and technology development in ocean, offshore, arctic, and related fields. Its main goals are to provide a forum for timely and in-depth exchanges of scientific and technical information among researchers and engineers. It emphasizes fundamental research and development studies as well as review articles that offer either retrospective perspectives on well-established topics or exposures to innovative or novel developments. Case histories are not encouraged. The journal also documents significant developments in related fields and major accomplishments of renowned scientists by programming themed issues to record such events.
