摘　　要：基于三维势流理论的频域方法,考虑稳定鳍对船体运动的影响,对某小水线面双体船稳定鳍的波浪载荷进行了长期预报和短期预报,将短期预报结果与试验结果进行了对比分析,验证了载荷预报方法可行性和一定的准确性.将稳定鳍设计载荷施加到局部结构模型,分析其应力结果,总结了稳定鳍及其加强结构的应力分布规律.Based on the frequency domain method of the three-dimensional potential flow theory and considering the influence of the stable fins on the hull motion,the long-term and short-term prediction of the wave load of the stabilizing fins of a small waterplane catamaran were carried out,respectively.The short-term forecast results were compared with the test results,and the feasibility and accuracy of the load forecast method were verified.The design load of stable fin was applied to the local structural model to analyze the stress results,and the stress distribution law of stable fin and its reinforced structure was summarized.
