Abstract

The invention relates to a method for fault diagnosis and additive repair of a ship mooring system, which mainly uses three-dimensional scanning reverse engineering technology and additive manufacturing technology, selects the relative zero point coordinates of the ship mooring system, and three-dimensionally measures the characteristic size of the windlass and its key point coordinates , three-dimensional measurement of the characteristic size of the guide chain roller and its key point coordinates, three-dimensional measurement of the coordinates of the upper and lower points of the anchor chain barrel and the inner and outer diameter of the anchor chain barrel, three-dimensional scanning of the surface point cloud data of the anchor lip, and the anchor lip The shape point cloud data is processed, and the computer virtual simulation anchor test is carried out. The anchor lip is applied to the rotary 3D printing equipment for layered additive manufacturing. Finally, the mooring system is assembled to complete the error diagnosis and repair of the ship's mooring system. The invention has the advantages of accurately diagnosing and repairing the faults in the design stage, and making up for the defects in the current ship mooring construction, which has very important significance for the error control of civil ship construction and warship construction error control.

Description

technical field [0001] The invention belongs to the field of ship mooring system construction, and in particular relates to a method for fault diagnosis and additive repair of ship mooring system. Background technique [0002] It is difficult to control the construction accuracy of the anchor seat, anchor lip, anchor chain barrel and chain guide roller in the current ship mooring construction process. Especially for the anchor lip, once there is a construction error, it will seriously affect the bonding state of the anchor and the anchor lip. The anchor lip needs to be redone if necessary. At present, there are related ship precision construction methods: [0003] The patent for invention with the application number CN201010188201.0 is a segmented construction accuracy control method of a cylindrical ultra-deep sea drilling platform. It provides a method for solving the accuracy control of the main hull of a large drilling platform in current ocean engineering, and provide...
