摘要/Abstract

摘要： 系留系统包含系缆和系留体两部分，分析波浪扰动力对系留系统运动参量的影响需要建立适用的系留系统运动模型。依据牛顿第二定律建立系缆的纵向运动控制方程，在此基础上采用集中质量法建立系缆的离散运动数学模型。基于刚体动量定理及动量矩定理建立回转体型系留体的纵向运动方程。联立系缆和系留体运动模型并补充相应的边界方程即得到系留系统纵向运动模型。采用4阶RungeKutta法对二级波浪力作用下的系留回转体系统进行了运动仿真，仿真结果显示系留系统在波浪力作用下做周期性摆动。

Abstract: A mooring system usually contains a tether and a mooring body. The motion equation of mooring system should be developed to research the kinematic parameters of the mooring system under the effect of wave. Based on the Newton’s Second Law, a governing equation of tether is established. Moreover a discrete motion equation of tether is deduced through the lumped mass method. According to the momentum and angular momentum theories of rigid body, a longitudinal motion equation of the rotary mooring body is developed. The mooring body model and the tether model constitute the longitudinal motion equation of mooring system together with the added corresponding boundary equation. In the end, the simulation example is simulated by using the 4th order RungeKutta method. The results show that the mooring system periodically sways under the effect of wave.
