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.
