The design of port mooring system is related to the safety of ship docking and is one of the hotspots in the ship and ocean engineering research.In previous studies, less consideration was given to dynamic loads.In this paper, the design of port mooring system is studied on the basis of dynamic load. Firstly, the force situation of steel pipe, steel drum, heavy ball, welding anchor and anti-drag anchor is mainly analyzed, and then the system force situation model is established based on the force balance equation and the catenary model, using genetic algorithm for numerical simulation;finally, the inclination angle of steel pipe and steel drum, the chain shape, the draft depth and swimming area of the buoy are obtained by MATLAB programming, and the influence degree of each influencing factor on the mooring system is discussed.%港口系泊系统的设计关系到船舶停靠的安全问题,是船舶与海洋工程研究的热点之一,以往的研究中,对于动荷载的考虑较少.在动荷载的基础上研究港口系泊系统的设计,首先,分析了港口系泊系统主要组成的钢管、 钢桶、 重物球、 电焊锚链和抗拖移锚的受力情况;然后,基于物体受力平衡方程以及悬链线模型建立了系统受力模型,采用遗传算法进行数值模拟求解;最后,通过MATLAB编程得出了在不同情况下钢桶、 钢管的倾斜角度、 锚链形状、 浮标的吃水深度和游动区域,并讨论了各影响因素对系泊系统组成部分的影响程度.
