摘　　要：提出了一种基于精确底质力时历的沉船打捞系统动力特性分析方法.通过对一个典型案例的模拟,初步阐明了离底提升阶段母船和系泊缆、提升缆之间复杂的相互作用模式,发现了在提升阶段母船运动,特别是纵荡运动出现了显著的异常增大.为了更好地控制母船在打捞过程中的运动,还对打捞系统的系泊布置进行了优化,得出了进行提升时运动控制效果更好、系泊张力更小的系泊缆布置构型.In this paper,a method for analyzing the dynamic characteristics of the sunken ship salvage system based on the accurate time history of the seabed resistance force is proposed.The simulation of a typical case preliminarily clarifies the complex interaction mode between the mother ship(a barge),the mooring line,and the lifting line in the lifting stage.It is found that the motion of the mother ship,especially the surge motion,has significantly increased in this stage.In order to better control the motion of the mother ship in the salvage process,the mooring arrangement of the salvage system is also optimized in this paper,and the mooring line arrangement configuration with better motion control effect is obtained.
