| Modern aircraft manufacturing and assembly process, large parts of the aircraft turning technology is used more and more, and the increasingly high degree of automation and, especially in the plane of the Department, assembly process, such switching technique of large parts of the aircraft docking assembly, lifting flip and attitude adjustment for plays a more and more important role.In this paper summarizes the domestic and foreign aircraft manufacturing technology development present situation foundation, combined with C919 aircraft wing box under the framework of the process characteristics, analyzes the design ideas and difficulties of the wing box frame turning device, and briefly describes the design goals of the turning device. First, the parts of the three-dimensional solid modeling using CATIA part design module, application module assembly completed the virtual assembly under the wing of the plane and turning equipment, detailed analysis was carried out on the device structure and lifting flip principle, and use the software analysis module and motion simulation module, in the 3D assembling model based, the space interference analysis and electronic prototype of the motion simulation analysis Secondly, using the MSC. Patran finite element analysis software, analyzes and studies the major parts stress distribution and stiffness, strength, and the optimized design of the device structure, and through the device structure calculation and analysis, the main product of the equipment selection In the end, the equipment is processed and manufactured. And before use by simulating flip test false parts, the test to verify the strength of the principle of equipment and turningThe through analysis and Research on t he C919 aircraft outer wing box reversing device design, computer simulation, manufacturing, commissioning, testing and so the accumulated complete design and technical information and experience, to follow up other models of aircraft assembly parts, especially tilting wing provides good engineering examples and references, the turning technology and application of popularization and application in the development of subsequent aircraft types, to improve our aircraft manufacturing technology level has important practical significance... |
