给出基于悬链线方程的深水单根忽略弹性的多成分系泊缆的静力分析方法,并以一工作水深为1000 m的两成分系泊验证该方法的正确性。运用迭代法和二分法相结合的计算方法准确、快捷地得到系泊缆形状关键数据,绘制悬链线图,完成系泊的静力分析。最后计算工作水深为2000 m的三成分系泊缆的静力特性,并给出张紧状态时的水平预张力。
The static analytical method based on catenary equation of single deep water multi-component mooring which ignores elasticity is presented in this paper. A two components mooring whose working water depth is 1000 m was analyzed to verify the correctness of the method. Using the method combining the iterative and dichotomy, a more accurate mooring line's shape could be accurately and quickly gotten. Based on the mooring's critical data, the catenary map could be accurately drawn to complete static analysis of mooring system. Finally, the static characteristics of a three-component mooring line whose working depth is 2000 m is calculated. Then the horizontal pre-tension force of the tension state is given.
