大型组块拖航运输强度分析研究

摘要

采用基于频域分析的设计波法，对某大型组块运输进行三维全耦合数值模拟和计算分析，把驳船和组块作为一个整体结构，计入驳船的柔度对组块的结构强度的影响，建立总体结构模型和水动力模型，采用SESAM软件包的多个软件程序进行数值模拟，确保运动分析和结构计算的准确性。%The three-dimensional fully coupled global strength analysis of a large topside transportation vessel is carrier out by using design wave method based on frequency domain analysis .Interaction between the topside and barge is accounted for by including for the flexibility of barge in the structural analysis .The global structural model and the hydrodynamic model are estab-lished, multiple software programs of SESAM package are used to ensure the accuracy of motion analysis and structure calcula -tion.
