| 摘 要： | 参考某海洋地震多分枝拖曳线列阵具体参数和该拖船的海浪响应幅值算子(RAO),结合该船工作时的具体过程,利用大型水动力分析软件Orca Flex建立了多分枝线列阵回转过程时的动力学分析简化模型,实现了对多分枝拖曳线列阵在回转过程中的动力学分析,得到了波流联合作用下,各个拖缆的张力和曲率沿缆长方向的变化规律及各个缆索拖曳点End A和拖曳缆索拖曳尾端End B的张力值在时域上的变化图像。结合计算结果,给出了多分枝拖曳线列阵在回转过程中的优化设计方案。

| Abstract: | Based on the parameters of the seismic streamer cables for a certain multi-branches towed array and the response amplitude operator(RAO) of the ship, combined with the specific process of the ship turning manenvers, the model of the multi-branches towed array has been established by OrcaFlex. And the dynamic analysis of the system has been made. At the same time ,we got the effective tension and curvature of every streamer cable along the length direction. And the tension of end A and end B of each cable in time history have been discussed . According to the calculated result, the optimization design of the multi-branches towed array during ship turning maneuvers has been given. |
