Research And Development Of Aircraft Wing-fuselage Automatic Connection Simulation System

Traditional aircraft large parts connection methods can not satisfy modern large aircraft parts connection. Therefore large parts automatic connection technology becomes essential to R&D of large aircrafts in china. R&D for wing-fuselage automatic connection technology is extremely complicated which involves comprehensive disciplines and requires to manufacture and re-design a number of Physical Prototypes for automatic connection program verification, which results in high costs, long cycle and low efficiency of automatic connection technology R&D. Based on simulation of ADAMS, the Paper builds simulation model for wing-fuselage automatic connection; optimizes trajectories of fuselage and wing; R&D simulation system for wing-fuselage automatic connection. with wing-fuselage automatic connection simulation system, this paper verifies connection process, connection strategies and algorithms; analyzes feasibility of wing-fuselage automatic connection scheme in real wing-fuselage; finally, applicability and effectiveness of wing-fuselage automatic connection simulation system applied in R&D of wing- fuselage automatic connection by wing-fuselage automatic connection physical prototype. The paper focuses on follows topics:(1) Wing-fuselage automatic connection simulation model is built and optimized so that real process of wing-fuselage automatic connection can be accurately reflected.(2) Strategy of wing-fuselage automatic connection is researched. Posture and position adjustment trajectories of fuselage and wing are optimized in order to improve stability of connection parts.(3) Wing-fuselage automatic connection simulation software is designed and developed. Automatic connection simulation system is researched and developed combined with co-simulation between ADAMS and MATLAB, through which Wing-fuselage automatic connection software can control automatic connection simulation model.(4) Based on wing-fuselage automatic connection simulation system, connection process, strategy and algorithm are verified, this builds the foundation for physical prototype verification and actual wing-fuselage automatic connection.
