摘要
针对利用线性模型忽略浮力解决系泊系统中锚链形状参数时所造成误差大的问题,提出考虑浮力的迭代模型。利用该模型,首先计算得到的锚链形状,其与真实情况相比所得结果基本相同;然后研究改变锚链链环型号对锚链形状的影响;最后,在以往的线性模型的基础上做出改进,得到锚链模型。通过对几个模型的比较可以发现,迭代模型和改进后锚链模型均与真实锚链形状相符,没有改进的模型与其有较大的差异。
For the large errors caused by the problems of the cable shape parameters of the mooring system solved by the linear model, the buoyancy iteration model is put forward. By using the model, the cable shape is firstly calculated. Its results are basically same with the real situation. Then the effect of the changes of chain link type on the cable shape is studied. Finally, based on the previous linear model, the anchor chain model is obtained. By comparing with several models, it can be found that the iterative model and the modified anchor chain model are consistent with the real chain shape, and there is no significant difference between the improved one and the improved one.
