中文摘要：
在满足锚链使用要求的情况下,为更好地改变锚链的受力特性,有必要分析并掌握多段悬链的锚链特性和锚泊力。给出多段锚链受力的计算步骤,并应用切比雪夫拟合锚链的受力,采用高阶边界元求解势流理论下的浮体波浪力,应用于锚泊与浮体结构系统运动数值模拟。通过算例验证模型的正确性,比较频域模拟和时域模拟锚泊系统的差异,得到关于锚链几何非线性的影响效果。
英文摘要：
In order to meet the requirements of the mooring lines with better force characteristics, the characteristics and forces of the multi-section mooring lines are analyzed as necessary. The calculation steps of multi-segment of mooring lines are introduced and the Chebyshev polynomial is applied to fit the force of mooring lines. Some fitting results are used in mooring-floating model, and the wave force of floating body is calculated by high order boundary element method. The accuracy of the models is verified through an example. The influence of the geometric nonlinear is compared in frequency-domain model and time-domain model.
