摘　　要：海洋浮标是一种布放在特定海域的观测装备,常用于定点观测风、浪、流、海温等海洋气象要素。本文对浮标浮体和锚系分别进行受力分析,给出了浮标在风、流、浪联合作用下的泊稳条件。采用Python编程语言编写了一套浮标抗风等级计算程序,可以计算特定浮标系统所能抵御的最大风级,以及特定风级下浮标系统泊稳所需的最小锚重,并通过一个浮标在台风天气下走锚的实际案例对程序计算结果进行了分析。计算结果还表明,海浪对浮标的作用力为流作用力的7～10倍,为风作用力的36～106倍,其作用在浮标受力分析和计算中不可忽略。本研究可为海洋浮标系统的布放设计和维护提供参考。Ocean buoys are observational equipment for monitoring meteorological elements in the specific sea areas. According to its force balance, the mooring condition of the buoy under the combined action of wind, current and wave are given. In this article, the programming language, Python, is used to calculate the maximum anti-wind level of the buoy and the minimum anchor weight required for stabilizing a given buoy system at a particular wind level. An actual buoy dragging case in a typhoon is given to analyzes the results of our program. The result shows that the wave force on the buoy is 7 to 10 times of current force and 36 to 106 times of wind force, which should not be ignored in force analysis and calulation. The method could provide experience for the future deployment design and maintenance of the ocean buoy system.
