高速三体船波浪设计载荷比较研究

摘要

This paper gives the prediction of wave loads for a trimaran by means of 3 dimensions frequency domain and rules. Short term predictions and long term predictions of loads are then available. The short term response for wave loads is calculated according to P-M double parameter wave spectrum. The longterm re-sponse for wave loads is calculated according to Rec.34 standard wave statistic of IACS. And the results are compared with the model test, that can know the bad situation of the trimaran. According to this paper, load characteristics of the fast trimaran can be understood to help further optimization of the structures.%文章根据现有的关于某三体船的相关资料和海浪统计资料，采用三维频域方法及劳氏规范计算该三体船设计波浪载荷，三维统计分析时短期预报采用P-M双参谱，长期预报采用IACS推荐的Rec.34标准海浪统计资料。然后把统计分析结果同模型试验结果对比分析，可给出三体船的波浪载荷特征，为三体船设计载荷相关规范的修正、模型试验方法的优化与理论计算的改进提供参考，也为有限元分析、结构设计和结构的进一步优化设计提供了依据。
