Research Of Aircraft Assembling Visualization System For Aircraft Cargo Door

Airplane assembly is an important link in the product life cycle,which is closely related to the products performance,quality and other factors.At present,the airplane assembly process design mostly used 2d drawings for the basis,but the effect is poor.Three-dimensional model can image,visual representation of the assembly process,and easy to understand.Therefore,the study of three-dimensional visual simulation system have Theoretical significance and value in use for the study of the assembly process,ensure assembly quality.The paper estab lished visualization assembly simulation platform by com bining with engineering application.W ith a certain type of aircraft cargo door,I have finished its visual display based on the digital m odel,the assembly simulation,the basis of interference.The main job is as following:Firstly,it is based on a deep research on dig ital assembly technology and the research at home and abroad situation.Then it is concluded that the domestic discussed in the engineering practice,especially the deficiencies in the assemb ly simulation of visualization.After all of this,I expounded the purpose of the research,the meaning and content.Secondly,the key technologies(including model lightweight technology,product structure tree and craft structure tree dynamic management technology)is advanced at the background of facing the engineering applicati on,in-depth understanding of visualization assem bly simulation technology system,and according to the system structure problems in practical application.Then,the paper built the visualization assem bly simulation system platform,including its hardware,software design.The feasibility of visu alization assembly simulation system platform is validated by some practical examples.Finally,some useful conclusions is advanced by the full summ arized,and puts forward the direction of further research work.Some measures are brought forward for the building of visual platform and function modules,which are based on th e basis of comparative analysis.It also has some certain reference value for the whole system development.
