Research On Flexible Tooling Design And Optimization Of Aircraft Panel Assembly

Aircraft digital flexible assembly technology is an advanced assembly technique, it isable to adapt to the requirements of rapid development, production, manufacture costdegradation and tooling equipment modularization and reconfigurable. In the current domesticbackground of greatly developing the digital flexible assembly technology, design andapplications flexible tooling, combine with our tooling design and application status, based onthe structure of the traditional tooling, we research on the aircraft panel assembly toolingdigitized and flexible design, and introduce the CAE technology to analyze and optimizetooling structural, to carry out tooling lightweight and low-cost research furtherly. The maincontents are as follows:Analyze and study the structure and composition of the aircraft fuselage typical panels,and its various components machining processing, and study the panels assembly process,choose an advanced assembly process based on the DA-hole assembly. According to therequirements of automated production lines and the assembly process to design the tooling.Study the working principle of panel assembly tooling reconfigurable and digitallycontrolled process when the panel is assembling completed the flexible tooling generalstructure design of aircraft panel. Take Y-mechanical transmission for an example to choosethe ball screw and servo motor.Study the ANSYS and finite element analysis methods, according to the finite elementanalysis requirement to research on tooling structure discretization, according to thediscretization analysis results to build a tooling structure modeling and carry out the staticstress analysis in the ANSYS.Study the basic theory of ANSYS optimization design and the zero-order algorithm,first-order algorithm. The tooling structure size is optimized to achieve a lightweight designrequirements based on ANSYS.
