Simulation Of Typical Aircraft Wing Assembly Based On Virtual Reality Equipment

Aircraft assembly in the whole process of aircraft manufacturing accounts a large proportion.The traditional assembly methods cannot meet the needs of enterprise development.Aiming at the shortcomings of the traditional aircraft assembly system,this paper focuses on the assembly of a typical aircraft wing in an immersed virtual environment.The human-computer interaction assembly system based on virtual reality equipment is developed under Unity platform.The main research contents are as follows:1?The modeling theory and method of virtual hand are studied.The geometric model and motion model of the virtual hand are established,and the motion map of human hand to virtual hand is realized by virtual reality interaction device.2?The virtual hand grasping of virtual objects is studied.The theory of collision detection and the method of crawling were analyzed,the directional bounding box collision detection method and the improved crawling rule are used to realize the virtual hand crawling.3?The class structure of the virtual assembly system was designed.The research on assembly modeling,assembly sequence planning,and human-computer interaction was carried out.The method of virtual assembly modeling was used to solve the problem of information loss in the virtual system.The method of component recognition and disassembly was used to divide the assembly sequence and through the knowledge of human-computer interaction researched,the virtual human was used for the manipulation of virtual objects in the virtual environment.4?Finally,the assembly of a typical aircraft wing was used as a specific example,for verification of the virtual assembly system developed.
