海洋资料浮标锚泊系统的系泊力计算

为了准确预报海洋资料浮标的受力及运动情况,建立了浮标锚泊系统的运动方程,提出了在海洋环境中作用在浮标及锚系上的各种外载荷的计算方法,得到了浮标的运动方程以及锚系的受力表达式。在计算锚泊系统的外载荷时,考虑了作用在锚系上的海流载荷以及由波浪载荷引起的波频运动对锚系的影响。通过算例在时域内对浮标锚泊系统的运动和张力进行了数值模拟计算,结果表明,该方法满足海洋工程中对浮标系统运动和受力分析的精度要求。

Mooring force calculation of ocean data buoy mooring system

We established the motion equation of ocean data buoy mooring system to accurately forecast the stress and movement of a data buoy.We presented the calculation method of all external loads on a data buoy and its mooring system.We also obtained the motion equation of a data buoy and the stress formula of its mooring system.We considered the impacts of ocean wave load acting on the mooring system and the wave frequency motion caused by wave load on the mooring system when calculating the external forces of the mooring system.Numerical simulation was conducted in time domain for the motion and tension of a mooring system.Results show that the approach can satisfy the required precision of buoy motion and force analysis in ocean engineering.
