系泊、拖曳、潜器脐带缆统一参数分析法

A Parameter Studying Method on Mooring,Towing and Submersible Umbilical Cables

提出了一种能统一处理系泊、拖曳、脐带缆静态构形和张力计算的参数分析法。缆索为三维,受载为流体力和多点载荷扰动,不计水面波浪动态激励以及流速的变化,并用三参数函数导出一个半解析公式。只要提供不同种类的边界条件就可进行数值求解,从而统一解决了实际海洋缆索静态缆力、缆形计算,可用于初步设计阶段理解各参数之间的相互影响以及每个参数的作用。

Presents a parameter studying method which can be used to deal with mooring, towing and submersible umbilical cables in three dimensions. The loads are fluid and multipoint loads disturbing. Dynamic surface wave excitement and current speed changing was ignored. A semianalytical formula is derived as a function of only three parameters which can be solved numerically by implementing different kinds of boundary conditions. So as to solve static tension of practical ocean cable and its underwater shape. The method can be used to understand effect on parametrics and its action for preliminary design.
