| 摘 要： | 本文以英国南海岸处Ｓｈｏｒｅｈａｍ港内系泊船为例，研究了港口内靠码头系泊船运动的数值计算问题。该船的实船实验和模型实验已经完成，为验证本文计算结果提供了依据。运动方程在时域内求解。在计算船体脉冲响应函数时，引入了船体阻尼系数在频率很低时的渐近表达式和一迭代算法。分析了港内共振波浪和其对船体的作用力。讨论了靠码头系泊船运动的非线性特征。计算结果与实验结果符合很好。

| Abstract: | A numerical simulation of a ship moored against a solid quay within harbour is studied in this paper. The moored ship is in shoreham harbour located in the south coast of U. K.,for which field data and physical model data are available to validate numerical vesults. Motion equations of a moored ship are solved numerically in time domain, an interation method and asymptotic expressions derived in the paper for damping coefficients at very low frequency are introduced in calculating impulse response functions of ship motions. The wave field in the harbour is analysed based on wave measurement by means of the resonant standing wave patterns of the harbour. Nonlinear features of moored ship motions are discussed.Numerical results of ship movements agree well with field data and experimental results. |
