摘　　要：在海底电缆抢修任务中,针对多层海底脐带缆的切割需求,提出一种基于水下机器人作业的水下液压剪切机构。结合海底脐带缆多层复合及金属绞线的特殊结构建立剪切失效模型,并对水下液压剪的切割机构进行设计。运用Abaqus软件分析切割过程中脐带缆的力学响应,对脐带缆逐层连续变化的力学特性进行研究,提出海底脐带缆切割需要满足的剪切力及水下液压剪机构的主要参数。In the task of repairing submarine cables,an underwater hydraulic shearing mechanism based on underwater robot operation is proposed to meet the cutting requirements of multi-layer submarine umbilical cables.Combined with the special structure of the multi-layer composite of the submarine umbilical cable and the metal stranded wire,the cutting mechanism of the underwater hydraulic shear is designed,and the mechanical response of the umbilical cable during the cutting process is analyzed by the Abaqus software.The continuously changing mechanical characteristics of the submarine umbilical cable is studied layer by layer.The shear force required for cutting the submarine umbilical cable and the main parameters of the underwater hydraulic shearing mechanism are proposed.
