摘　　要：针对目前海上补给装备研制中尚无可用的高架索模型的现状,从多体动力学角度入手,研究了绳索多体系统动力学模型的建立方法,将绳索均匀划分为若干刚体单元,各单元之间采用球铰连接。用该方法建立了绳索的多刚体系统动力学模型,并在此基础上,应用仿真软件ADAMS对海上横向干货补给过程进行仿真计算。结果表明:海上补给高架索多刚体系统动力学模型完全可以模拟实际的高架索,且仿真计算结果与高架索力学振动模型的计算结果相比更贴近实际情况。As for an overhead cable model for engineering practice, the ways to establish a multi-body system dynamics model of rope are studied. A rope is divided into a number of rigid units and two adjacent units are connected with a ball hinge so as to establish a multi-rigid dynamics model of rope. The model is used to simulate the alongside dry cargo replenishment at sea by means of the software ADAMS. The results show that the multi-rigid-body system dynamics model of highline can simulate the actual overhead cable and that the calculation results are closer to the actual situation than the results of the overhead cable mechanical vibration model.
