摘要
本文在静力计算的基础上，应用三维势流理论数值计算程序计算浮标体的附加质量（矩）、阻尼系数和所受波浪力。采用美国数据浮标中心（NDBC）提出的分析方法，即将锚泊线动力方程线性化，并考虑到锚泊线与浮标体之间相互耦合的关系，在频率域中对单点系泊浮标进行了动力分析。文中还提出了当锚泊线中间有集中质量（悬挂重量或浮球）时相应的处理方法，因而不仅适用于简单的单点系泊浮标的动力分析，也适用于水平系泊浮标的动力分析。文中对三种典型的海洋资料浮标进行了考核计算，计算结果与试验结果比较有较好的一致性。
Based on static analysis, the added mass and added damping of a buoy are calculated by three dimensional potential flow numerical calculation program. The method proposed by NDBC is used to solve the dynamic problem of moored buoy. In this method, the dynamic equations of mooring line were linearized while the interaction between buoy motions and cable motions is taken into consideration. Also a method to handle a mooring line with concentrated mass along it is proposed. Calculated results are presented for comparison with the experimental ones.
