摘　　要：系泊系统是近浅海观测网的重要组成部分,如何设计最优的系泊系统从而促进信号的传播具有重要的意义.本文围绕着系泊系统的设计问题展开讨论,通过三力汇交平衡理论和力矩平衡方程确定系泊系统中各个参数之间的联系,利用悬链线方程解得锚链的受力、形状,解决了在确定锚链的型号、长度和重物球的质量的情况下,使得浮标的吃水深度和游动区域及钢桶的倾斜角度尽可能小的问题,给出了最优系泊系统设计的方案.Mooting system is an important part of near shallow sea observation network, which promotes the spread of signals. As a consequence, designing an optimal mooring system is of great significance. In this paper, our objective is to build a mathematical model to develop a best design for the system. Firstly, we analyze the rela- tionship among the parameters in the mooring system by the three-force convergence theory and the moment balance equation, and get the force and shape of the anchor chain by the catenary＇ s equations. Then we determine the type and the length of the anchor chain, as well as weight of the heavy ball. Based on the above conditions, we calcu- late the draft depth of the buoy, the swimming area of the buoy and the tilt angles of steel drums. In addition, we also consider that the values of the parameters are changed due to different wind speeds and sea speeds. Hence, we use the multi-objective optimization scheme to constrain the angle and ultimately obtain an optimal design of the mooring system.
