Large-size airplane parts digital assembly technology

To solve the difficult problem in assembling large-size airplane parts,a Flexible Assembly Technology System(FATS) integrated with many advanced digital techniques was presented.Through analyzing and expounding the system concepts and composition,the flexible assembly workstation prototype for major-parts assembly was set up.Based on this,four primary supporting techniques were summarized and expounded.Hereinto,the assembly process simulation technique was based on digital mock-up,and its application features and existing difficulties in airplane parts assembly were explained.Concept of Digital Master Tooling(DMT) was brought forward while overcoming the shortcomings of traditional entity master tooling.The fashion and function of mechanical follow-up positioning device,as well as its two kinds of control software,were explained.In addition,the application of laser tracking measurement technique,including its effect,principle and measuring method in the major-parts docking assembly was explicated.
