中文摘要:海上遇险目标的搜寻是开展海上搜救工作的前提,其中海上遇险目标漂移轨迹的预测准确性至关重要。以3种海上遇险目标共5种遇险姿态为研究对象,设计基于风浪流水槽的漂移运动物理模型试验。首先,进行受力分析和漂移驱动树分析的预设计;其次,基于相似准则按特定的缩尺比进行3D打印制作海上遇险目标模型,设计不同风、浪、流条件下的59种工况;最后,完成共计659次的漂移运动试验,其中包含单因子驱动试验和多因子耦合驱动试验。结果表明,水槽模型试验的结果与前人外海试验的结果基本符合,说明物模试验设计较为合理可靠,能够在风浪流水槽中准确地复现海上遇险目标的漂移运动。该物模试验设计可为海上遇险目标漂移运动的研究工作提供新的试验思路。

外文摘要:The search for targets in distress at sea is a prerequisite for maritime search and rescue(SAR)operations,in which the accuracy of drift trajectory prediction is crucial.Taking three types of maritime distress targets and five distress postures as the research objects,a physical model experiment for drift motion using a wind-wave-current flume was designed.First,a pre-design involving force analysis and drift-driving tree analysis was conducted.Then,based on the similarity criterion,the appropriate scaling ratio for 3D printing to produce the distress target models was calculated.A total of 59 working conditions were designed under various wind,wave,and current scenarios.In total,659 drift motion experiments were conducted,including both single-factor and multi-factor coupling driving tests.The results show that the flume model experiments results are generally consistent with previous offshore experimental results,indicating that the physical model design is reasonable and reliable.It accurately reproduces the drift motion of maritime distress targets in a flume of wind,wave and current,offering a new experimental approach for related research.
