| 摘要: | 以海洋石油720的多分支水下拖曳系统为工程背景, 建立了多分支拖曳线列阵模型, 并利用orcaflex软件模拟并分析了系统在不同的波高和流速下的稳定性, 进而对船舶拖曳线列阵的首段张力极值、首段张力幅值差以及尾端振动极值进行了研究. 得到了系统在使用水鸟的情况下可以提高稳定性且系统稳定性不受其本身的弯曲刚度、扭转刚度和轴向刚度的影响, 最后对拖曳线列阵的实际应用提出了建议. |
| Abstract: | With offshore oil 720 multi-branch underwater towing system as the engineering platform, a Multi-branch towing linear array model is established using the orcaflex software to analyze the stability of the system under a variety of environmental circumstances. In this paper, the tension extreme value at the start of the rope, and the tension amplitude difference at the end of the rope of the ship are studied. To validate the method for improving the stability of the system, MATLAB software is adopted for rendering data analysis which may offer guidance for the practical applications to the design of towing linear array |
