The Overall Design Of The Hull Assembly Of Three-dimensional Fast Installation Positioning System&Research On The Key Technologies

In the traditional ship assembly process, lots of auxiliary work such as assembly typeshelves and installation templates were used to locate and support ship parts, throughmanual operation to achieve docking. This model exist some shortcomings like lowassembly accuracy, complex adjustment, unstable quality, high labor intensity and longworking time. To solve the problems, domestic shipbuilding enterprises have established a3D design system in ship construction work and made exploration of virtual assemblyalgorithm and technology on above bases. However, due to the lack of accuratemeasurement and precise positioning and scribing work equipment for intermediateproducts in the construction site, it’s still unable to apply the installation and positioninginformation which produced in virtual assembly system to actual construction processeffectively, making the virtual assembly application effect in ship block assemblyrestricted extremely. From that point, in order to solve this problem, Ship block assemblyof three-dimensional fast installation positioning system was proposed.In this paper, completion of the overall design of the ship block assembly ofthree-dimensional fast installation positioning system, and research on some of the keytechnologies in the system. Firstly, introduce and analysis some of the key technologies.Secondly, carry on the design of the whole system and the division of subsystems，Dividedit into three-dimensional digital field measurement subsystem, spatial orientationsubsystem, robot control subsystem and the robot body subsystem, and select permanentmagnet after compare adsorption modes of the robot. Thirdly, design and developmentVirtual assembly simulation database which provided a guarantee for the source of thedata of field measurements of three-dimensional digital subsystem design. Finally, designthe Prototype system for spatial orientation subsystem and achieve the function thatpositioning Indoor.The main purpose of this paper is to complete the overall design and research someof the key technology, and provide a basis for follow-up study.
